摘要: In falling film evaporation process, the heat is transferred from condensing fluid side to liquid flowing on evaporating side. Tube geometry and tube size have an important role performance of evaporators. The current article presents a two-dimensional computational dynamics study water thermal spray metal coated vertical corrugated conduits. Two-phase flow simulation carried out by using finite volume method-based commercial software, k-ω equations with shear stress transport. Sinusoidal corrugations different porosity been selected for this study. Heat mass transfer during are included through user defined functions. Effect Reynolds number, wall superheat, surface roughness coefficient presented. Numerical results compared horizontal circular tube, as well plate conduits literature. An enhan...
