1. 1. Development of a CFD Boundary Condition to Simulate a Perforated Surface

   University essay from Umeå universitet/Institutionen för fysik

   Author : Medet Kiflemariam; [2021]
   Keywords : Computational Fluid Dynamics; CFD; Boundary Condition; Bleed; Aerospace Engineering; Aeronautical Engineering; Physics;

   Abstract : In aircraft with jet propulsion engine intakes at supersonic speed, strong pressure waves referred to as shockwaves occur, which may interact with any present boundary layers along the intake surface. The adverse pressure gradients associated with Shock Wave-Boundary Layer Interaction (SWBLI) may cause boundary layer flow separation, which can result in disturbances of the flow that can be harmful to the device or decrease engine performance.

3. 2. Pressure Effects in Orifice Cavitation Modeling

   University essay from Umeå universitet/Institutionen för fysik

   Author : Henrik Sjöholm; [2020]
   Keywords : Fluid mechanics; Cavitation; Orifice plates;

   Abstract : In this thesis computational models for cavitating flows around orifice plates has been studied and compared. The goal was to fit a model with experimental data and this was done with some success, although problems with numerical stability, long calculation times and geometry overfitting remain. READ MORE
