Résumé

The thermal-hydrodynamic characteristics of a single-phase turbulent flow in chevron-type plate heat exchangers with sinusoidal-shaped corrugations have been numerically investited in this article. The computational domain contains a corrugation channel, and the simulations adopted the shear-stress transport k-E model as the turbulence model. The numerical simulation results in terms of Nusselt number and friction factor were compared with limited experimental data and existing correlations in order to verify the accuracy of the numerical model. The validation was performed using single-phase water as the working fluid. A bi-objective optimization was carried out using an appoximation-assisted optimization technique, which provided considerable computational savings to ensure the feasibility of optimization.
