A simulation of a radiator used for passive cooling of microelectronic devices has been performed using in-house code `TCLB` developed in the Division of Aerodynamics. The solver utilizes Lattice Boltzmann Method. It is designed to run parallelly on HPC clusters and supports multi-GPU computations. Colors corresponds to the magnitude of the velocity field in lattice …

Hydrodynamic stability in undulated channels

Nektar++ has been used to study various forms of hydrodynamic instabilities arising is a flow through a channel with corrugated walls. Stability analysis has been performed using direct numerical simulation and tracking growth, or attenuation of the unstable modes. We ware able to show that, in the case of the large scale wall undulations applied …
