The important matter of mixing at both micro and macro-fluidic levels has to be studied for determining how to achieve proper stirring ways. In order to analyse this matter, the first problem was how to visualise and especially how to measure the stirring process in a certain flow. In this study, the behavior of viscous glycerin employing various stirring patterns was investigated. The changes in glycerin solutions were observed by means of streamline flow topology and particle track arising from four variations in configurations: the same stirring directions of rod and vessel (RUN 1), opposite stirring directions of rod and vessel (RUN 2), stationary rod and rotating vessel (RUN 3), stirring rod and stationary vessel (RUN 4). The flow pattern was analyzed with ANSYS computational fluid dynamic tool. The simulation results shows that the opposite direction stirring pattern configuration produced more vortices than those of the same direction stirring patterns and the stirring rod pattern generated more vortices in almost all parts of the vessel than stationary rod pattern.

The Impact

Aiming at the high-power low-speed marine diesel engine, the paper analyzes the impact of the diesel engine’s cooling to the power, economy and NOx’s emission, studies the variable flow control method and system of the diesel engine cooling water and proposes the scheme setting up the intercooler system and the body cooling system independently in the diesel engine. The results show that the methods and systems are better to improve the engine power, reduce the fuel consumption and NOx’s emission.

Main Engine

This paper investigates the installed performance of the ETF40B marine gas turbine engine (MGTE) on SLEP LCAC. Historical estimates of intake and uptake losses for SLEP LCAC have proven inaccurate, resulting in loss of available power for hump transition. A recent computational fluid dynamic (CFD) analysis of the uptakes revealed a possible 1000% increase in actual uptake losses. NSWCCD was tasked to evaluate and correct these detrimental deficiencies. This paper documents the development of the performance testing and results. Specifically, NSWCCD performed CFD analyses of the uptake configuration, designed pressure/temperature rakes, developed a unique DAQ schema, and statistical analysis of the average engine based upon acceptance test procedures (ATP), and generation of new torque tables based upon the LCAC drive train limits.
