Simulation of Two-Phase Flow with Sub-Scale Droplets and Bubble Effects

We present a new Eulerian-Lagrangian method for physics-based simulation of fluid flow, which includes automatic generation of sub-scale spray and bubbles. The Marker Level Set method is used to provide a simple geometric criterion for free marker generation. A filtering … Continue reading

Real-Time Fluid Simulation Using Discrete Sine/Cosine Transforms

Recent advances in fluid simulations have yielded exceptionally realistic imagery. However, most algorithms have computational requirements that are prohibitive for real-time simulations. Using Fourier based solutions mitigates this issue, although due to wraparound, boundary conditions are not naturally available, leading … Continue reading
