Graphics processing unit accelerated lattice Boltzmann method simulations of dilute gravity currents

Lattice Boltzmann method models offer a novel framework for the simulation of high Reynolds number dilute gravity currents. The numerical algorithm is well suited to acceleration via implementation on massively parallel computer architectures. Here we present two lattice lock-exchange currents, in which largest turbulent length scales are directly resolved. three-dimensional simulations accelerated by exporting computations graphics processing unit and validated against experiments high-resolution numbers up 30,000. achieve equivalent accuracy conventional large eddy prediction key flow properties. A conservative analysis computational performance relative methods indicates that presented reduces times orders magnitude. Therefore, it can be used as foundation development depth-resolving capture more complexity environmental
