Abstract

Due to the enormous heat generated in the internal combustion engine of a motor vehicle, a cooling system must be included. For compact and aerodynamic cars design affect the air flow rate through the radiator and need the design of compact radiator. The radiator is device used to cool the engine. In any cooling system of a motor vehicle, a redesigned the radiator can give the better performance. This report examines fluid flow characteristics in curved tubes heat exchanger by numerical method. This project will investigate the result for the curved tube radiator and compare to result from existing radiator. The method of this study for the collecting data and analyze by numerical method. By using the Computational Fluid Dynamic (CFD) software the modeling of fluid flow in tube was developed for computation simulation. Aided by the developed software, the characteristic of fluid flow will be investigated. Besides that, this study will be carried out by using experimental data for evaluating the working performance of different types of radiator. Therefore, performance data of automotive radiator were acquired and analyzed to improve available radiator performance. Performance data of curved tube radiator such as velocity, mass flow rate, pressure, temperature, air flow rate were acquired to find out the effect of the operating parameter to radiator performance. The heat dissipation rate of the radiator increased as air flow rate and surface tube are increase. Meanwhile, the expected result for the performance of a curved tube radiator associates with more heat dissipation and compact design and can be used in automotive cooling in the future.
