Systolic Cycle

The aim of this work is to tune the lattice Boltzmann BGK (LBGK) simulation parameters in order to achieve optimum accuracy and performance for. time dependent flows. We present detailed analysis of the accuracy and performance of LBGK in simulating pulsatile Newtonian flow in a straight rigid 3D tube. We compare the obtained velocity profiles and shear stress to the analytic Womersley solutions. A curved boundary condition is used for the walls and the accuracy and performance are compared to that obtained by using the bounce-back on the links. A technique to reduce compressibility errors during simulations based on reducing the Mach number is presented.
