EFFECT OF MESH, BOUNDARY CONDITION AND TURBULENCE MODELS ON TURBULENT SEPERATED FLOW OVER A FORWARD-BACKWARD-FACING STEP
CFD investigation of mesh, boundary condition and location, and the effect of turbulence models on the turbulent separated flow over a forward-backward-facing step. A numerical model was set up to replicate and compare with the model in the literature. The Reynolds number, Re, is 1.7E5 based on step height 50 mm and obstacle length L = 10H. The freestream velocity of air at the inlet is 50 m/s. The simulation was performed using the ANSYS software.
Numerical Investigation of Mesh Material Properties on Heat Convection and Conduction of a Vertical Impinging Round Jet onto a Horizontal Surface (Stationary and Moving)
Using Computational Fluid Dynamics (CFD), this paper investigates the effect of mesh material properties on the heat convection and conduction (fluid-solid interaction) of a vertical impinging round jet onto a stationary and moving horizontal surface, as well as the effect of conjugation in the solid domain. This paper is an excerpt from an assignment in Numerical Thermoflow that was completed in 2021 during my Bachelor of Science Honours in Applied Science Mechanics at the University of Pret...
DEVELOPMENT OF A CASSAVA MASH SIEVING MACHINE FOR GARI PROCESSING OPERATIONS
Limited or poor food separation techniques into fine particles for further processing cause post-harvest losses of food crops and initiates the problem of food and nutritional insecurity in Nigeria. In order to solve this problem, food crops need to be processed into a lasting and nutritious consumable form through the use of mechanization. Different materials in powder form or solid form are separated by using two-level screening machines. This machine can be used in different industries lik...
