Week 4.1 - Solving second order ODEs

Deriving 4th order approximation of a 2nd order derivative using Taylor Table Method.  Taylor series formula is a representation of any function as an infinite sum of terms. These terms are calculated from the values of function’s derivatives at a single point. The derivative of a function f at the point x is defined…

  Challenge No-6 Graphics Card Simulation. Aim – Perform a steady state conjugate heat transfer analysis on a model of a graphics card. Challenge Objective – 01.   Run the simulation by varying the velocity from 1m/sec to 5m/sec for at least 3 velocities and discuss the results. 02.  …

Challenge no- 5 Rayleigh Taylor Instability   Aim – The Aim is to understand the Rayleigh Taylor instability phenomena and how it takes place. Objectives – 1.      What are some practical CFD models that have been based on the mathematical analysis of Rayleigh Taylor waves? In…

Challenge – CHT Analysis on Exhaust Port. Objective 1 – Conjugate heat transfer refers to the combined analysis of both fluid flow and heat transfer in systems where there are solid structure interacting with the fluid flow, leading to heat transfer between the solid structure and the surrounding fluid. In…

  Challenge: External flow over an Ahmed’s Body.   Q1. Describe Ahmed’s body and its importance. Ans. The Ahmed body represents a simplified, ground vehicle geometry of a bluff body type. Its shape is simple enough to allow for accurate flow simulation but retains some important features relevant…

Challenge No- 2 – Flow Over a Cylinder.   Geometry Creation: We have created the geometry by the geometry tools in the Ansys Space claim. Circle Diameter – 2 Meter Geometry length – 60 Meter Geometry width – 20 Meter After geometry creation, we have to make this geometry a solid plane. For…

  Challenge No-1 Mixing tee Long. Aim : 01.   Set up a steady state simulation to compare the mixing effectiveness when hot inlet temperature in 36’C & the cold inlet is at 19’C. 02.   Try both the K-epsilon & K-omega SST models, which one is better for the simulation. 03.  …

TOPO (Topo > Faces > Topo) – In starting, it was seen that, there are multiple of single coons present in the car body. So, we have…

Ansa Challenge – 3 CFD mashing on turbo charger Turbo charger is used in automobile, where exhaust energy from engine is used for creating more suction inside intake manifold of the engine. Geometry Checks: Before doing meshing activity, geometry checks are done for checking any single coons & triple coons in the object.…

Ansa challenge – 2   In this challenge, there is a valve like object. On which we have to perform meshing. There are multiple of patches found in the surface of the body, so we have to fill those patches. Checks: There are multiple checks in the ansa software. So that we can check objects irregularities. There…

FILE PARSING: File parsing is a process of analyzing a string of symbols, either in natural language, computer language or data structure conforming the rules of a formal grammar. The term parsing comes from the Latin pars (orations), meaning part of speech. With in computational linguistics the term is used to refer to…

A genetic algorithm (GA) is a method for solving both constrained and unconstrained optimization problems based on a natural selection process that mimics biological evolution. The algorithm repeatedly modifies a population of individual solutions. At each step, the genetic algorithm randomly selects individuals from the…

  A pendulum is a body suspended with a string to move freely back and forth under the influence of the gravity. When a pendulum is displaced from it’s equilibrium position, it is subjected to a restoring force due to gravity, that will accelerate it back towards the equilibrium position. When, we have the second…
