摘要

This paper presents a three dimensional analysis with the computational fluid dynamics CFD code of a turbulent flow through a plate heat exchanger with corrugated wall. For the calculation, the standard k-ε model with "wall-functions" is employed with Reynolds number Re range of 400, 900, 1000. This paper describes the effect of rib height on the thermal performance of the PHE. To simulate the flow through a corrugated plate and discover the flow characteristics and structure, the commercial CFD software Ansys Fluent R15.0 is used. In order to simplify the simulation, the computational domain was considered as one corrugated plate with chevron angle β = 45°. The geometry is obtained by the Computed aided design software Solidworks. It consists of chevron plate with different rib height h of 3, 5, 7 mm and a constant chevron angle β = 45°. The hot water enters the fluid domain with temperature of 60°C through the corrugated wall which has a constant temperature of 20°C. The contours of temperature, velocity and turbulence intensity were presented and analyzed numerically.
