Heat transfer analysis of forced convective flow within an enclosure

Abstract

The paper is to study about the movement of heat analysis with respect to forced convective flow within sideways four-sided enclosure. The mathematical statements of the flow variables are represented using a discrete quantity by virtue of upwind control volume scheme. Non-dimensional parameters are suitably preferred so as to determine Nu. This Nu for the sake of different fluids are calculated by using a suitable empirical correlation and thereby the transfer of heat between the top wall and forced convective flow of these fluids is examined. It is ascertained that, a substantial rise in Nu and hence the transfer of heat within the four-sided enclosure by way of forced convective flow of any fluid substantially increases within the sideways four-sided enclosure. The average Nusselt numbers for fluids such as air and water at different Rayleigh numbers of 1, 10, 100, 1000, 1700 in the range of Ra ≤ 1708 are calculated and observed to increase linearly.
