Cfd Simulation Of Impinging Jet Flows And Boiling Heat Transfer, Mehrdad Shademan Jan 2015

Cfd Simulation Of Impinging Jet Flows And Boiling Heat Transfer, Mehrdad Shademan

Electronic Theses and Dissertations

Circular jets impinging vertically on flat surfaces have many practical applications in industry. Nozzle height-to-diameter ratio plays an important role in the performance of this type of jet. In this thesis a step by step approach has been followed to cover different aspects of impinging jets. In the first step, a steady Reynolds-Averaged Navier-Stokes simulation has been carried out on impinging jets with different nozzle stand-off distances. A strong dependency of the jet characteristics on the nozzle height-to-diameter ratio was observed. The simulations show that an increase in this ratio results in larger shear stress and more distributed pressure on ...


Virtual Methodology For Predicting Whistling Noise Over The Front Grill Of A Vehicle, Tyler Bevan Jan 2014

Virtual Methodology For Predicting Whistling Noise Over The Front Grill Of A Vehicle, Tyler Bevan

Electronic Theses and Dissertations

This research presents an approach in predicting the presence of a noise source generated by the external flow around a fin-like member of a vehicle front grill. The goal was to determine if a low-resource computational method could be used to capture the pressure fluctuations related to the noise frequencies audible during experimental evaluations on the geometry. Two nearly identical profiles were studied where would generate wind noise in the presence of high velocity flow and the other would not. Several simulations were run on both shapes in four arrangements using incompressible and compressible solvers in attempts to determine an ...
