Week 2 - Flow over a Cylinder.

Aim: Run a simulation of combustion using methane as the fuel in the combustor model. Objectives: Part I: Perform a combustion simulation on the combustor model and plot the variation of the mass fraction of the different species’ in the simulation using line probes at different locations of the combustor as shown…

Aim:To perform a parametric study on a gate valve at different valve opening settings. Theory: Gate valves work by inserting a rectangular gate or wedge into the path of a flowing fluid. They are operated by a threaded stemwhich connects the actuator (generally a hand wheel or motor) to the stem of the gate. If the valve…

Aim: The goal of this project is to analyse a cyclone separator and determine the separation efficiency and pressure drop. Objective:1. To describe four empirical models used to calculate the cyclone separator efficiency in a few words.2. To determine the separation effectiveness of a specific cyclone separator model by…

Aim: To perform CHT analysis on Graphics card. Objectives: Perform Simulations by varying the velocity from 1 to 5 m/s for a minimum of 3 values. Find the Max Temperature and Heat Transfer Coefficient of the system Prove Convergence of the simulation by using plots and graphs. Identify hotspots on the object. Theory: CHT…

Aim: To conduct the Rayleigh Taylor Instability CFD simulation. Indroduction: Rayleigh Taylor Instability occurs at the interface of fluids with different densities. The less denser fluid pushes the more dense fluid in an attempt to reduce its combined Potential Energy. Theory: The early disruptions of the RT instability…

CHT analysis: CHT stands for Conjugate Heat Transfer Analysis. This type of analysis allows for simulation of heat transfer between Solids and Fluids by an interchange of thermal energy at its interfaces. CHT analysis is used to create simulations of heat exchangers, cooling of electronic equipment and general-purpose…

Ahmed Body: It is a simplified car model which captures the external flow around the model. It is primarily used to validate the CFD results of a virtual model and the results obtained in the wind tunnel of a real model. The negative pressure in the wake region is due to the air flowing over and under the model. The air…

Aim: To simulate the flow over a cylinder and explain the phenomenon of Karman vortex street. Conditions: i)To calculate the strouhal number @ reynolds number, Re=100 , in steady and unsteady case. ii)To calculate the coefficient of drag and lift over a cylinder by setting the Reynolds number to 10,100,1000,10000 &…

Aim: to perform steady state fluent analysis on a mixing tee pipe using the conditions given. Conditions given: two mixing tees of different lenghts different temperatures at both inlets, 19 celsius @ cold inlet and 36 celsius @ hot inlet velocity of fluid @ inlet is fixed at 3m/s, velocity of fluid @ cold inlet is varied…
