Sinopsis

One of the most popular kind of compact heat exchangers is cross corrugated plate. The thermal and hydraulic performances of cross corrugated plates are strongly influenced by geometrical parameters. Computational fluid dynamics is used to investigate the performance of cross corrugated plate heat exchangers with triangular corrugation. More specifically the influence of the apex angle on the flow and heat transfer characteristics is studied while the corrugation angle is unvaried. In order to solve the transitional flow regime, the Reynolds stress model is used. For a periodic unitary cell of the triangular cross corrugated plates, several three dimensional simulations are carried out. The numerical results are in a good agreement with existing experimental correlations. The results are discussed for different heat and flow characteristics such as Colburn j factor and friction factor variation with respect to the apex angle. Moreover, several correlations are proposed to predict the Colburn j factor and friction factor for different corrugation angles in transitional flow regime.
