AbstractNumerical simulation using Computational Fluid Dynamics (CFD) method is one way of predicting airflow characteristics on the model. This method is widely used because it is relatively inexpensive and faster in getting desired results compared with performing direct testing. The correctness of a computational simulation output is highly dependent on the input and how it was processed. In this paper, simulation is done on Onera M6 Wing, to investigate the effect of a turbulence model’s application on the accuracy of the computational result. The choice of Onera M6 Wing as a simulation’s model is due to its extensive database of testing results from various wind tunnels in the world. Among Turbulence models used are Spalart-Allmaras, K-Epsilon, K-Omega, and SST.Keywords: CFD, fluent, Model, Turbulence, Onera M6, Spalart-Allmaras, K-Epsilon, K-Omega, SST.AbstraksSimulasi numerik dengan menggunakan metode Computational Fluid Dynamics (CFD) merupakan salah satu cara untuk memprediksi karakteristik suatu aliran udara yang terjadi pada model.

Abstract Oxygen isotope analyses of diagenetic cements can provide detailed evidence of sedimentary burial processes and conditions, as the δ18O values of precipitating minerals reflect contemporaneous local δ18Owater and temperature conditions. Uncertainties in the timing and rates of pore water δ18O evolution in sedimentary basins can complicate interpretation of these records. Fracture-bridging (0.5–1 mm) quartz cements observed in sandstones of the Cretaceous Travis Peak Formation in the East Texas basin show clear growth-zoning by cathodoluminescence and contain detailed fluid inclusion records of temperature that make them excellent candidates for interrogating prolonged histories of basin temperature and the evolution of δ18O in basin pore water. New secondary ion mass spectrometer (SIMS) δ18Oquartz isotopic data from fluid inclusion-rich quartz bridges in Travis Peak sandstones record a steady increase of pore water δ18O values from ∼5 to 7‰ (VSMOW; Vienna Standard Mean Ocean Water) as the sandstone warms from ∼130 to 150 °C. To help evaluate whether this trend could be generated solely from local water-rock interactions in response to burial compaction, a one-dimensional closed system isotopic burial model was created to simulate how δ18Owater values change in a quartz-dominated sandstone during diagenesis. Using both directly measured and inferred rates of Travis Peak compaction, the magnitude of change in δ18Owater that we calculate from quartz bridge geochemistry cannot be reasonably modeled solely by local quartz mechanical compaction, pressure solution, and cementation processes, necessitating significant fluxes of silica and high-δ18O water from outside of the sandstones prior to maximum burial. This indicates that even units which appear surrounded by significant barriers to fluid flow (i.e., mudrock-bounded channel sandstones) may have been infiltrated and diagenetically modified by large fluxes of fluid on geologic time scales.

Current exploration for oil is being conducted by governments, major integrated oil companies, independent oil companies and syndicates, all of whom have different interests. The interdependence of the various aspects of exploration, production, transportation, refining and consumption within the oil industry is obvious; but the interdependence of the producing, transit, refining, and consuming countries has only recently been realized by the world. Within the exploration branch of the oil industry the mutual dependence of geological and geophysical methods has become generally accepted over the past thirty years. Good early training and collaboration along the whole chain of exploration can solve many industrial problems, and education can solve the world‐wide problems between countries

The 90th anniversary of the founding of our Society is coming up on 11 March 2020. In 1930, SEG was established at a time when the integration of geophysics — specifically, seismic and gravity — into oil exploration dramatically improved discovery successes. The amazing accomplishments and forethought of those groundbreaking pioneers in the early 20th century positioned our profession extremely well to be not only significant but vital to meeting the energy needs of the world over the last 100 years. Today, it is extremely rare that a production well is considered, much less drilled, without geophysics.

Structural Failures

Thunderstorm downburst is a sort of outburst strong wind on or near the ground, and its wind field characteristics are significantly different from boundary layer winds. The study on its effect on the structures was relatively rare, nevertheless numerous structural failures around the world caused by thunderstorm were found. Computational fluid dynamics (CFD) was employed for this stationary downburst simulation, also the wind pressure distributions of the curved-roof in this flow had been surveyed by varying the parameters of the structure. The results show that the wind attack angle has significant effect on the wind pressure of curved-roof, so does the ratio of the rise to span. The predominant impacts of the ratio of wall height to span and the roof span were found at the windward side. Furthermore, by locating the roof beneath the downburst jet, the wind pressure distribution of the roof was also investigated to reveal the significant effects caused by vertical wind of downburst.

Hovercraft operates on multi-terrains such as on water surface, on roads, on mud, on non-flat surfaces... it is used popular on the world. With the ability of operating on multi-terrains at high speed, hovercraft is used for many purposes, such as on surveying and rescues missions on areas that are not reachable by normal vehicles, on military missions and traveling... Currently, methods for estimating hovercraft resistance are not accurate enough due to many experiential formulae and coefficients involved during calculating process. This paper presents a method for calculating hovercraft resistance using computational fluid dynamics (CFD) tools. This research method is used popular and modern research method on the world. The method was applied for calculating resistance of a 7 meters length hovercraft model. The modelling results give us suggestions in selecting engine power and operating speeds for minimizing fuel consumption.

Gum guar is an economically important pulse crop of Indian economy. Keeping the importance of gum guar production in to consideration the present study was undertaken to investigate the growth in gum guar area, production and productivity in India and along with peeping into the export trends of gum guar production from India. In order to fulfill the objectives of the study, secondary data on gum guar area, production, productivity and export scenario were obtained from various sources for India. The results of the study brought out that the total gum guar area, production and productivity of gum guar in India is positive with 5.30, 10.87 and 2.84 per cent, respectively from 2005-06 to 2014-15. Also, the export growth in volume and value terms is positive with 18.62 and 48.6 per cent during the same period. The increased export growth in gum guar is mainly attributed to its increasing demand from oil exploration and shale gas production in the world.

 INTISARIKomputasi dan eksperimental dalam dunia teknik permesinan (mechanical engineer) merupakan bidang yang saling melengkapi. Komputasi dilakukan untuk memberikan gambaran dan penjelasan rasional dari fenomena yang dihasilkan pada eksperimen. Komputasi juga memberikan prediksi sebelum dilakukan eksperimen untuk lebih mematangkan kondisi-kondisi dari sebuah eksperimen. Komputasi dengan metode Lattice Boltzmann adalah metode yang relatif baru dan menjanjikan di dunia komputasi aliran fluida atau CFD (Computational Fluid Dynamics), sebagai alternative metode yang sudah lama dikembangkan dari persamaan kontunum Navier-Stokes. Metode Lattice Boltzmann berangkat dari logika interaksi sekumpulan partikel dan ditelusuri pola interaksinya melalui bantuan pola jaringan (lattice). Pada riset ini akan digunakan metode Lattice Boltzmann untuk membuat model matematis dan algoritmanya pad aliran fluida yang mengalir di sekitar External Ballistics model G1-Standard-Bullet. Tahap riset selanjutnya adalah pengembangan pembuatan coding pemrograman dan simulasi visual untuk mengetahui pola aliran dan analisis-analisis aerodinamisnya. ABSTRACTComputational and experimental in the world of mechanical engineering is a complementary field and providing a picture and a rational explanation of the phenomena generated from the experiment. Computation with the Lattice Boltzmann method is a relatively new and promising method in the world of fluid flow computation or CFD (Computational Fluid Dynamics), as an alternative to the long-established method of the Navier-Stokes continuum equation. The Lattice Boltzmann method departs from the logic of the interaction of a set of particles and traces its interaction pattern through the aid of a network pattern (lattice). In this research we will use the Lattice Boltzmann method to create a mathematical model and algorithm for the flow of fluid flowing around External Ballistics model G1-Standard-Bullet. The next stage of research is developing the development of coding programming and visual simulation to know the flow pattern and aerodynamic analysis.
