About

iTurbo

This app simulates fluid dynamics by solving Navier-Stokes equations for 2D incompressible turbulence. It uses a direct numerical simulation method with Euler time stepping and Fourier space calculations for efficiency.

Highlights
  • Direct Numerical Simulation (DNS)
  • Navier-Stokes equation solver
  • 2D incompressible turbulence
  • Euler time stepping
  • Fourier space calculations
  • Vorticity field transformation
Features
Read full description

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.

Verdict

The call

iTurbo and Bernstein are too close to call on the numbers: across 5 compared parameters — price, ads, in-app purchases and device support among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.
