Dr. Anand’s research activities are in the areas of heat transfer and aerosols. His past and current research sponsors include the U.S. Nuclear Regulatory Commission, Texas Higher Education Coordinating Board (TATRP and ERAP), EG&G Rocky Flats, ASHRAE, NASA Center for Space Power,U.S. D.O.E-NETL, ANUIES-Mexico, and King Fahd University, Saudi Arabia.
Dr. Anand has made contributions in both the heat transfer and aerosol fields. These include the numerical modeling of conjugate heat transfer with applications to cooling of electronic equipment, heat transfer in serpentine channels, condensation of non-CFC refrigerants in smooth horizontal tubes, and modeling of transport of aerosols through sampling lines. The current focus of Dr. Anand’s research is simulation of mixed convection over a 3-D horizontal backward facing step, heat transfer over a flat tube bundles, and heat transfer in 2D and 3-D channels with porous baffles.
Implicit Runge Kutta Methods to Simulate Unsteady Incompressible Flows:M. Ijaz and N.K. Anand
A Semi Implicit Pressure Linked Equations Diagonally Implicit Runge Kutta (SIMPLE DIRK) method for transient incompressible viscous flow simulation is developed. The proposed method can be used to achieve arbitrarily high order of accuracy in time-discretization which is otherwise limited to second order in majority of the currently available simulation techniques. A special class of implicit Runge-Kutta methods is used for time discretization in conjunction with finite volume based SIMPLE algorithm. The algorithm was tested by solving for velocity field in a lid-driven square cavity. This method was developed for both staggered and co-located grid lay outs.
Mixed Convection Over a 3-D Backward Facing Step:A finite volume code was developed to simulate mixed convection over a conducting horizontal backward facing step. Simulations were carried out for Re=200 and Ri (Richardson number) was varied from 0 to 3. The buoyancy effects on a flow over a backward facing step were found to move the edge of the recirculation zone further upstream. Numerical results may serve as benchmark for future work.
Heat Transfer over a Flat Tube Bundle:Flat tubes are preferred to circular tubes in heat exchanger applications because: (a) larger heat transfer contact area and (b) less vibration due to smaller downstream recirculation bubble. A finite volume based code was developed to predict heat transfer over a flat tube bank. An algebraic technique was used to generate the body fitted grid and problem was solved in terms of contra-variant variables. The code validated by comparing results for flow over a series of circular cylinders confined in a parallel plate channel.Distinctions
