Finite element method for the heated Newtonian fluid inside a connected optical cavities

Abstract

The engineers are fascinated in fluid flows and heat transfer in engineering optics and devices. For such purposes, fluid flows are computed in different geometries. The engineers normally look for reduced heat transfer, enhanced cooling rate and reduced friction drag. Thus, the focus of the present article is to undertake the flow of viscous or Newtonian fluid through joined cavities which is very important in many engineering fields. The Navier-Stokes equations are operated for studying behavior of flow, while Fourier's law of heat conduction is employed for the analysis of heat flow in connected cavities. The consequences show that high pressure, lowest velocity and high temperature are observed at the thin connection of cavities.
