Simulate The Behaviour Of Fluids, Such As Liquids And Gases(CFD) Using MATLAB

Introduction

MATLABSolutions demonstrate In this project we are going to work on the two-part having the computational fluid dynamic concepts, in first part we will solve the simple initial value problem and study the variation of the parameters on the power generated by the electric generator, we used mathematical model of the system and solve it numerically. In second part we will deal with hydrodynamic force on a square prism, we solve the 2D problem using the numerical approach and compute the force and drag exerted on the prism for various size and using the pressure and shear stress data we can compute the drag coefficient and lift coefficient over the period of time, lastly Strouhal number is calculated by computing the frequency of vibration of the lift force.

In order to simulate the behaviour of fluids, such as liquids and gases, in various physical and engineering applications, computational fluid dynamics (CFD) is a branch of study that integrates ideas from physics, mathematics, and computer science. These simulations can help engineers build and improve products and procedures by illuminating the dynamics of fluid flow. The initial value issue, which requires resolving the equations of motion for a fluid at a certain initial time given beginning circumstances like initial velocity and initial pressure, is one of the fundamental CFD problems. Transient fluid flows, such as those that happen during system startup or shutdown, are frequently studied using this kind of issue. The fluid's equations of motion must be discretized using numerical techniques like the finite difference method or the finite volume approach in order to solve an initial value issue using CFD. These techniques reduce the equations to a set of algebraic problems that a computer can answer using iterative algorithms. The numerical approach chosen, the simulation's spatial and temporal resolution, and the complexity of the physical model used to explain the fluid motion are some of the variables that affect how accurate the simulation is. Additionally, it's crucial to validate the simulation results to make sure they concur with experimental findings or theoretical hypotheses
