Heat Transfer Analysis Of Slot Jet Impingement Onto Roughened Surfaces, Rashid Ali Alshatti
USF Tampa Graduate Theses and Dissertations
The effect of surface roughness on jet impingement heat transfer was investigated in this research. A numerical analysis was conducted for free surface slot jet impinging normally onto a heated plate. Six different geometries and three different plate materials were investigated. The cooling fluid used for the analysis was water, and the flow was laminar with a range of Reynolds number (Re) from 500 to 1000. Temperature distribution, local and average heat transfer coefficient, and local and average Nusselt number were presented for each case.
The steady state heat transfer results show that the increase in Reynolds number (Re) increases …
