(4 Questions)
- Q1. How to measure convergence?
- Ans.
Convergence in CFD analysis is measured by checking if the solution is not changing significantly with each iteration.
Convergence is typically measured by monitoring residuals of key variables (e.g. velocity, pressure) over iterations. When residuals reach a small, acceptable value, convergence is achieved.
Another method is to track the change in key parameters (e.g. mass flow rate, drag coefficient) between iterations...
- Q2. Experience with PowerFlow and ANSYS
- Ans.
Experience with PowerFlow and ANSYS
I have extensive experience using PowerFlow for fluid dynamics simulations
I am proficient in using ANSYS for structural analysis and thermal simulations
I have successfully integrated PowerFlow and ANSYS for multiphysics simulations
I have worked on projects where accurate CFD analysis was crucial for design optimization
- Q3. What is CFL number?
- Ans.
CFL number is a dimensionless number used in fluid dynamics to determine the stability of a numerical simulation.
CFL number stands for Courant-Friedrichs-Lewy number.
It is calculated as the product of the flow velocity, time step, and grid spacing, divided by the fluid kinematic viscosity.
A CFL number greater than 1 indicates that the simulation is unstable and may lead to inaccurate results.
A CFL number less than 1 en
- Q4. What is difference between RAN, LES and DNS
- Ans.
RAN, LES, and DNS are different approaches used in computational fluid dynamics (CFD) to model turbulent flows.
RAN (Reynolds-Averaged Navier-Stokes) models average the flow properties over time, suitable for industrial applications.
LES (Large Eddy Simulation) resolves large turbulent structures while modeling smaller ones, suitable for complex flows.
DNS (Direct Numerical Simulation) solves all scales of turbulence with...
