Numerical simulation on the effects of Ambient velocity and Temperature on solar panel efficiency

In desert regions like Thar located in India, the efficiency and capacity of solar panels is affected by many natural factors like wind velocity, surrounding temperature, dust, humidity etc. The main aim of this research is to find the temperature rise observed in solar panels due to surrounding temperature and wind velocity in the Thar Desert. A solar panel model is constructed for this research. The panel is simulated under three different velocities, 2.23m/s, 6.17m/s and 10.10m/s that are prominently observed in different months of a year in the Thar Desert. The surrounding temperatures considered for the simulation are 22.22°C, 30°C and 45°C respectively. Analysis results are obtained using Ansys simulation software. Based on the result, the ambient temperature and wind velocity can be determined to obtain best efficiency of the solar panel constructed in the Thar Desert.

Experimental verification of high-strength composite materials using a simulation program

The use of composites in engineering applications has been steadily growing in recent years. Despite this growth and despite some important advantages of the properties that composites offer, such as reduced weight, design freedom, etc., a breakthrough in high- volume components in engineering applications has not been achieved at present. Therefore, when designing selected parts and structures using new materials, such as composites, material and manufacturing costs must be considered a high priority if further significant growth is achieved. However, many other factors must also be considered when designing a composite part for engineering use. These factors also depend on the particular material or combination of materials being evaluated. The paper is focused on testing a composite material manufactured from polybutylene terephthalate (PBT), reinforced with high-strength fibres Cordenka and Aramid fibres. The composite material's mechanical properties were verified using Ansys simulation software.

Design and Simulation of a Piezoresistive v-Shaped Strain Gauge for Torque Measring

Modeling and simulation of system design adjustment is respectable training for design and engineering decisions in real world jobs. In this paper, the exact perseverance connected with the strain of components is very important for structural designs, analyses, and for excellent control. The information linked to this type of test is usually related to the exact dimensions connected with the pressure within a flexible region. This paper proposed the design and simulation of a torque sensor with a piezoresistive V-shaped strain gauge. The piezoresistive measure of a precious metal for a stable base was made according to the results of an ANSYS simulation. A torque sensor with a piezoresistive V-shaped tension measure on a base was made. The result of the particular simulation shifted the fraction of tension on the base to enable the torque on the substrate to be measured. Theoretical studies on the piezoresistive measure of a metal for the stable base as well as the torque sensor were introduced. A maximum of 127.29 με and a maximum resistance change in gauge equal to 0.091Ω were achieved for an applied torque of 22.0725 Nm. Here, computer systems modeling and simulation are going to be used.

Resolution-Enhancing Structure for the Electric Field Microsensor Chip

Electrostatic voltage is a vital parameter in industrial production lines, for reducing electrostatic discharge harms and improving yields. Due to such drawbacks as package shielding and low resolution, previously reported electric field microsensors are still not applicable for industrial static monitoring uses. In this paper, we introduce a newly designed microsensor package structure, which enhances the field strength inside the package cavity remarkably. This magnification effect was studied and optimized by both theoretical calculation and ANSYS simulation. By means of the digital synthesizer and digital coherent demodulation method, the compact signal processing circuit for the packaged microsensor was also developed. The meter prototype was calibrated above a charged metal plate, and the electric field resolution was 5 V/m, while the measuring error was less than 3 V, from −1 kV to 1 kV in a 2 cm distance. The meter was also installed into a production line and showed good consistency with, and better resolution than, a traditional vibratory capacitance sensor.

Research on “Cylinder-Four-Beam” Microstructure Improvement of MEMS Bionic Vector Hydrophone

The existing MEMS bionic vector hydrophone has the problems of low-sensitivity and narrow-working band, and the sensitivity and working bandwidth cannot be improved simultaneously by changing the single microstructural parameter. In this paper, the MEMS bionic vector hydrophone microstructural parameters (length, width and height of cantilever, side length of the center block, height and radius of the rigid cylinder) have been optimized simultaneously to obtain a higher sensitivity at the almost same working bandwidth. Firstly, through the mechanical analysis of the microstructure, the objective function and feasible region are established to optimize the parameters of the microstructure, and a set of optimized parameters is obtained. Secondly, the optimized structure is verified by ANSYS simulation, and then, the optimized four-beam structure is fabricated by the MEMS manufacturing technology. Finally, these two kinds of hydrophones (the previous one and the optimized one) are produced, and their performance tests are carried out. The testing results show that the performances of the optimized hydrophone have been greatly improved, exhibiting a receiving sensitivity of −181.2 dB@1 kHz (increasing by 6.5 dB, 0 dB reference 1 V/μ Pa), the frequency response ranging from 20 Hz to 1 kHz which is the same working bandwidth as before, and a good dipole directivity. The optimization researches in this paper provide a method and idea for the performance improvement of the following MEMS vector hydrophone.

Macro Modeling of V-Shaped Electro-Thermal MEMS Actuator with Human Error Factor

The V-shaped electro-thermal MEMS actuator model, with the human error factor taken into account, is presented in this paper through the cascading ANSYS simulation model and the Fuzzy mathematics calculation model. The Fuzzy mathematics calculation model introduces the human error factor into the MEMS actuator model by using the BP neural network, which effectively reduces the error between ANSYS simulation results and experimental results to less than 1%. Meanwhile, the V-shaped electro-thermal MEMS actuator model, with the human error factor included, will become more accurate as the database of the V-shaped electro-thermal actuator model grows.
