A presentation on final project“Non Premixed Combustion Analysis on SCRAM Jet”In partial fulfilment of the requirements for the award of merit certificate for course on Advanced CFD using ANSYS FLUENT  By-SRIJITH NAIR CONTENT Introduction Literature Survey Project Objective Methodology CFD result References…

Challenge on Combustion Lean premixed conventional micro-combustion and non-premixed flameless regime of methane/air are investigated in this project by solving three-dimensional governing equations. At moderate equivalence ratio standard k–ε and the eddy-dissipation concept are employed to simulate…

Gate Valve Simulation   A gate valve, also known as a sluice valve, is a valve that opens by lifting a barrier (gate) out of the path of the fluid. Gate valves require very little space along the pipe axis and hardly restrict the flow of fluid when the gate is fully opened. The gate faces can be parallel but are most…

Cyclone Separator   Part A- Four Empirical Models Used For Cyclone Separator Efficiency  Cyclones are devices that employ a centrifugal force generated by a spinning gas stream to separate particles from the carrier gas. Their simple design, low capital cost and nearly maintenance-free operation make them ideal…

Gearbox Sloshing Effect   In fluid dynamics, slosh refers to the movement of liquid inside another object (which is, typically, also undergoing motion). Strictly speaking, the liquid must have a free surface to constitute a slosh dynamics problem, where the dynamics of the liquid can interact with the container to…

Exhaust Port Challenge Part A Conjugate Heat Transfer The term conjugate heat transfer is used to describe processes which involve variations of temperature within solids and fluids, due to thermal interaction between the solids and fluids. A typical example is the heating or cooling of a solid object by the flow of air…

GRAPHICS CARD CONJUGATE HEAT TRANSFER ANALYSIS   Computational Fluid Dynmaics (CFD)and more specifically Conjugate Heat Transfer (CHT) analysis can accurately predict heat transfer by simultaneous solving all the relevant solid and flow field heat transfer processes, for example: conduction through solids, free and…

Rayleigh-Taylor Instability PART A- Two fluids of different densities superposed one over the other (or accelerated towards each other); the instability of the plane interface between the two fluids, when it occurs, is called the Rayleigh-Taylor instability. In the context of the Rayleigh-Taylor instability, there are…

Ahmed Body PART A- AHMED BODY The Ahmed Body was first created by S.R. Ahmed in his research “Some Salient Features of the Time-Averaged Ground Vehicle Wake” in 1984. Since then, it has become a benchmark for aerodynamic simulation tools. The Ahmed body is a generic car body (a simplified vehicle model). The…

Tee Mixing effectiveness Case 1- For case 1 steady state simulations is carried out on geometry Short mixing tee with hot inlet velocity of 3m/s and Momentum ratio of 2. Tee mixer is first modelled in ANSYS spacechain witin limited of the academic license and 3D model is shown below. In spacechain solid is suppressed and…
