| Abstract: | For the design of Heat Exchanger in EGR system, it is important on how to discharge the residual heat out of the power plant by heat exchanger in the way of natural convection circuit when the entire electricity of power plant is shut off. Fluent6. 0 was used as a tool to solve the problem. Provided with appropriate boundary conditions for tube-wall temperature and appropriate computation model in Fluent6.0, there search provided theoretic basis for the design and optimization of EGR Heat Exchanger |
