Combustion analysis using Eddy dissipation turbulence model

Aim: To perform conjugate heat transfer analysis on a graphic card Objectives: Run the simulation by varying the velocity from 1m/sec to 5m/sec for at least 3 velocities and discuss the results. Find out the maximum temperature and heat transfer coefficient attained by the processor. Prove that the simulation has achieved…

Aim: To perform a combustion simulation on the combustor model and to plot the mass fraction of different species at the different locations inside a combustor. Combustion: combustion is a high-temperature exothermic redox chemical reaction between fuel and air (primarily with oxygen) that produces a gaseous product as…

Introduction: The four models used for cyclone separator are: Iozia and Leith model: This model assumes that a particle carried by the vortex endures the influence of two forces; centrifugal and flow resistance. It considers simple force balance on the particle in the cyclone. It assumes that centrifugal force and drag…

Introduction: A gate valve, also called sluice valve, is a valve used to isolate the flow in pipeline. They are controlled either by clockwise rotation to close (CTC) or clockwise to open (CTO) rotating stem. When operating the valve the gate moves up and down on the threaded stem. It is preferred as it does not restrict…

Introduction: Rayleigh Taylor instability is observed at the interface of two different density fluids interacting with each other. This mixing example can be water suspended over air under the effect of gravity., where the air will penetrate the water forming bubbles and instability is observed. Some Practical CFD models…

Comment: ============================== The Strouhal number must be appx 0.16 for a flow over cylinder with renoylds number of 100. As it is not matching i deduct marks. ================================== Problem Statement: To simulate the steady and transient model for flow over a cylinder (Re=100) Input parameters: inlet…

Challenge-1 A comparative steady-state analysis of a mixing T pipe (as shown in fig 1) is done. Fig.1: T joint with hot and cold fluid (mixing) flow.   Three cases are analyzed as per the description below: Case-1: Short length pipe with hot inlet air (x-axis) inlet velocity of 3m/s and cold air (y-axis) inlet velocity…

1. Ahmed Body and its importance: The Amed Body was first described by S.R. Ahmed in 1984. Its layout is as follows: Three main features were seen in the wake: 1. The A recirculation region that is formed as the flow separates at the top of the vertical back surface of the model. 2. The B recirculation region is formed…

1. Conjugate Heat Transfer: Conjugate heat transfer corresponds with the combination of heat transfer in solids and heat transfer in fluids. In solids, conduction often dominates whereas, in fluids, convection usually dominates. Conjugate heat transfer is observed in many situations. For example, heat sinks are optimized…
