Abstract
Standard k-e two-equation model was used to simulate the complex fluid flow in a heat exchanger head. A baffle is set ahead of an outlet tube. The domain-extension method was adopted and conjugated computation was conducted. Implementation of wall-function method was proposed for analyzing the step-wise solid boundaries in the fluid region. Computational results show that baffle could enhance uniformity of the outflow velocity distribution.
