Numerical study on hydrodynamics and heat transfer of droplet arrays using grid generation

The objective of the present study is to employ the numerical grid generation technique for the solution of hydrodynamics and heat transfer in a three-droplet array. Elliptic partial differential equations are used to generate grids in the physical plane. The Navier-Stokes equations in vorticity-stream-function form and the energy equation have been solved numerically by finite difference method for Reynolds number range of 10 to 200. Numerical solutions in terms of drag coefficient and Nusselt number have been obtained. The results are compared with the results obtained in an earlier study as well as those in the literature
