Abstract

Contaminant that are recently discovered at the joint of large piping system and can caused defect to industrial product. A computational analysis using simulation of FLUENT software of the hydrodynamic contaminant removal with heat effect is executed and experiments are carried out in order to validate the flow structure past rectangular, triangular and semicircular cavity of length-to-depth ratio 2:1. Computational analysis is performed to analyze the heat transfer and flow field in a channel with cavity heated only at the bottom sides. The cavity that needed to test comes with three (3) types that are square, triangle and semicircle. Unsteady flow are using in this research to analyze the flow of streamlines and vortices pattern. The process of fluid dynamic in a cavity is modeled via a numerical solution of the Navier–Stokes equations with the energy equation for laminar flows. This research starts with the geometry creation. Contaminant was inside the cavities. In order to remove all of the cavities, hydrodynamic need to take part in this simulation. The hydrodynamic will flow from the inlet of the channel and make vortices to remove the contaminant from the cavities. The heat was applied at the bottom of the cavities to analyze if there had present of heat, the contaminant removal rate will be higher or vice versa.
