Week 6 - CHT Analysis on a Graphics card

IntroductionThe study focuses on simulating isentropic flow through a quasi 1D convergent divergent nozzle. Both conservation and non conservation forms of the governing equations are derived and solved using the MacCormack's technique. The primary objective include determining the steady stste temperature distribution,…

AIMTo solve the 2D heat conduction equation using point iterative techniques (Jacobi, Gauss-Seidel and Successive Over-Relaxation).First discretize the equation and then implement the iterative methods and also compare the convergence rates of these methods for steady state and transient analysis.1. Steady State AnalysisThe…

M = readmatrix('VI.xlsx','Sheet','Sheet1');   % read the excel sheet   x = (-17.3:0.1:0.9);                                   % create the value range with intervals y = interp1(M(:,1), M(:,2), x);     …

To derive the the fourth order approximation of the second order derivative using central difference and skewed difference scheme, Starts by defining the Taylor Expansion for the function `f(x)` and its derivatives at a point `x`. 1. Central DifferenceUsing Tayloe expansions, the central difference approximation for the…

Parametric Study On The Gate Valve Simulation A parametric study on a gate valve simulation involving the setting of the opening refers to the investigation of the valve's performance and behavior by varying the valve opening. The study aims to analyze how different opening positions affect the flow characteristics, pressure…

1) Empirical Models Used To Calculate The Cyclone Separator Efficiency Stairmand Model: The Stairmand model is a widely used empirical model that relates the collection efficiency of a cyclone separator to its geometric parameters, including inlet velocity, cyclone diameter, and particle size. It assumes ideal conditions…

CHT ANALYSIS ON GRAPHICS CARD Conjugate Heat Transfer (CHT) analysis of a graphics card involves studying the thermal behavior and heat transfer mechanisms within the graphics card assembly. This analysis considers both the solid components of the card as well as the fluid flow and heat transfer in the surrounding air…

1. Rayleigh Taylor (RT) Instability Rayleigh Taylor instability is a fluid instability phenomenon that occurs at the interface between two fluids of different densities, with the lighter fluid pushing into the denser fluid under the influence of gravity. The mathematical analysis of Rayleigh-Taylor waves has provided insights…

CHT ANALYSIS  A Conjugate Heat Transfer (CHT) analysis is used to study the combined heat transfer phenomena involving both fluid flow and heat conduction within solid structures. It is typically applied in situations where there is a strong coupling between the fluid and solid domains, and heat transfer occurs through…

Ahmed's Body And Its Importance Ahmed's body, also known as the Ahmed body or the Ahmed reference shape, is a simplified geometric model of a car body used in automotive aerodynamics research and testing. It was introduced by Professor S. R. Ahmed in the 1980s as a way to represent a generic sedan-shaped vehicle for studying…

Karman Vortex Street The phenomenon of Karman vortex street, also known as the von Karman vortex street, is a fluid dynamic phenomenon observed when a fluid, such as air or water, flows past a bluff body, causing alternating vortex shedding in its wake. This phenomenon was named after the Hungarian-American engineer and…

AIM To set up steady-state simulations to compare the mixing effectiveness of two Mixing Tees having different lengths.  Also evaluate which one is suitable out of k-epsilon and k-omega for this simulation. GIVEN DATAS Two mixing tees having two differen length is given. Hot inlet temperature is 36 0C. Cold inlet…

Consider a spring-mass damper system of mass 'm', spring constant 'k', damping coefficient 'c'. The force applied to the system is F(t) and the displacement is x. The equation of motion of the system is; m*x_dot_dot = c*x_dot = k*x = F(t) Applying Laplace transform on both side of this equation; X(s) = [F(s)+ms*x(0) =…
