Convergence rate of individual and global quantities in direct numerical simulations
Overview & Synopsis
Typical individual quantities in Direct Numerical Simulations of statistically steady flows are converging at a rate of 1/√ T , where T is the averaging time of the simulation. However, global quantities that represent integral momentum balance in the computational domain can exhibit a faster convergence rate of 1/T. This faster convergence rate is analysed and explained. Theoretical predictions are supported with a Direct Numerical Simulation.
