Seminar - Challenges and Recent Advances in Computation of Turbulent Jet Impingement Heat Transfer by Prof. Anupam Dewan

Date:   07 December 2012 (Friday)

Time:   2:30 pm – 3:30 pm

Venue:  EF305, The Hong Kong Polytechnic University

Abstract:

A review of the current status of computation of turbulent impinging jet heat transfer is presented. It starts with an introduction to challenges faced in computation of flow and heat transfer characteristics of jet impinging flows considering the simplest jet impinging geometry: normal impingement of a single jet into a flat surface. Subsequently, a review of recent computational studies related to the same geometry is presented. The effects of different subgrid scale models, boundary conditions, numerical schemes, grid distribution, and size of the computational domain adopted in various large eddy simulations of this flow configuration are presented. A review of direct numerical simulation of the same geometry is also presented. Further, some recent attempts in Reynolds-averaged Navier–Stokes modeling of impinging flows are also presented. The lecture also presents future directions in the computation of impinging flows. The lecture concludes with the presentation of results obtained by our group on computation of a turbulent slot jet impingement.
