Abstract:

In study, heat transfer from flat and triangular step pattern facets in channels with Dh jet inlet width was investigated using three air jet streams. The studies were carried out with the Ansys-Fluent computer program using the numerical time-independent and three-dimensional k-ε turbulence model. The channel facets are adiabatic and only the model facets have a constant heat flux. The outcomes of the work were matched with the scalar and empiric outcomes of the work in the litterateur, and it was achieved that they are comparable. The outcomes are performed as the mean Nu number and diversity of facet temperature for each model facet. Velocity-flow and temperature contour dispersions of the jet flow throughout the duct were commented for the model facets with distinct Re numbers and H/Dh ratios. It was interpreted that the Nuo number of the flat step patterned model facet at H/Dh=3 for Re=10000 is 45.18% higher than the triangular step facet.
