Use CFD (Computational Fluid Dynamics) technique to simulate the water jacket of 4G24 gasoline engine is an effective way to look into the internal flow status of the water jacket. After calculation analysis, it is found that part of regional flow rate is too low in the cylinder head and block water jacket, where is easy to form dead areas. The HTC (Heat Transfer Coefficient) on cylinder block intake...
The 3D computational domain model of a certain automobile exhaust system cold end was built by software UG, shaped grid by Gambit, numerical simulated by computational fluid dynamics software FLUENT. Analysis of the system's internal flow quality , indicated that the system's back pressure fulfilled the design requirements, the pre-muffler's internal flow field is smooth, but the main muffler's wall...
The aim of this project is to design and optimize the existing automobile radiator. The entire analysis is carried out using CFD (Computational Fluid Dynamics) with FLUENT (6.0.) as software. The main objective is to design the automobile radiator with surface area density (SAD) greater than 1000 m2//m3 with increased heat transfer coefficient, rate of Heat transfer, reduced cost and reduced weight...
Outdoor unit of household air conditioner is studied widely in household air conditioner parts. Optimizing it may improve air conditioner' EER (Energy Efficiency Ratio) better and make its cost lower than optimizing other parts can. To reduce the cost of the household air conditioner and improve its EER, this paper first studies the correlation among configuration of outdoor unit and heat transfer...

This paper documents the geometrical optimization of a micro-channel heat sink. The objective is to optimize (minimize) the wall peak temperature of the heat sink subject to various constraints such as manufacturing restraints, fixed pressure drop and total fixed volume. A gradient based optimization algorithm is used as it adequately handles the numerical objective function obtained from the computational...
