iTurbo vs Fluid Mechanics Practice

This application performs a Direct Numerical Simulation (DNS) where the Navier-Stokes equations are solved for two dimensional incompressible homogeneous turbulence. These equations are a set of nonlinear partial differential equations. The time stepping is performed with a simple Euler method where the time step is calculated so that the CFL number does not exceeds the given number (should be less than 0.8 otherwise the simulation blows up). The equations are solved in the Fourier space where the calculation of the nonlinear term transforms to a simple multiplication. The main CPU usage is consumed by transforming the vorticity field back and fourth between the Normal space where the time-stepping is performed and the Fourier space where the nonlinear term is calculated.

Fluid Mechanics Practice is an educational application designed to help students understand and practice fundamental concepts related to fluid behavior at rest and in motion. The app focuses on practice-based learning through chapter-wise quizzes, mock tests, and daily quizzes aligned with standard Fluid Mechanics curricula. Users can practice questions from individual chapters, attempt mock tests for overall assessment, and monitor their performance using statistics. The app supports self-study, classroom learning, and exam preparation for engineering students. Topics Included 1.
