Professor Peter Daivis will give a lecture about “Anisotropic heat flow in shearing fluids by molecular dynamics simulations” at PoreLab premises (Valgrinda, PTS2, 2nd floor) on Wednesday, October 2nd, at 13:00. Professor Daivis is coming from the School of Science cluster, Physics department at RMIT University in Melbourne, Australia. He is visiting PoreLab in Trondheim from Sept. 28th to Oct. 6th.
By simulating a simple fluid in a channel bounded by tethered atoms, the heat flux is computed for two systems: a temperature driven one with no flow and a wall driven, Couette flow system. The results for the temperature driven system give the Fourier’s law thermal conductivity, which is shown to agree well with experiments. Through comparison of the two systems, we quantify the additional components of the heat flux parallel and normal to the walls due to shear flow.
