Entropy generation in the Blasius flow under thermal radiation

Abstract

In this work, we examine the effects of thermal radiation and viscous dissipation on entropy generation in the Blasius flow. The governing boundary layer equations for the velocity and temperature fields are transformed into ordinary differential equations with the help of suitable similarity transformation and then solved numerically with the help of the shooting method. The expressions for the volumetric entropy generation rate and the Bejan number are calculated for thermal radiation. The effects of various physical parameters on the entropy production number, average entropy and the Bejan number are studied through graphs using velocity and temperature profiles. It is noticed that by increasing the thermal radiation parameter the entropy production in a thermal system can be reduced and viscous dissipation increases the entropy production.

Irreversibility Analysis of Dissipative Fluid Flow Over A Curved Surface Stimulated by Variable Thermal Conductivity and Uniform Magnetic Field: Utilization of Generalized Differential Quadrature Method

“…Makinde [3] reported the effects of variable viscosity on inherent irreversibility in a flow over a flat plate with Newtonian heating and uniform magnetic field. The combined effects of linear thermal radiation and viscous dissipation on entropy generation in a Blasius flow are reported by Butt et al [4]. Recently, Afridi and Qasim [5] examined the influences of frictional heating on entropy production rate in a three-dimensional flow.…”

Thermal analysis of an Eyring-Powell fluid flow-through a constricted channel

“…Readers are referred to a worth reading book by Bejan [11] on the subject for deep understanding of the subject. Afterwards, numerous investigators [12][13][14][15][16][17][18][19] further explored the phenomenon of heat transfer and entropy generation in convective heat flow problems under various physical assumptions. Souidi et al [20] conducted an entropy analysis for a peristaltic pump in a contracting tube.…”

Entropy analysis in moving wavy surface boundary-layer

“…Recently, Munawar et al [12] investigated the Second law analysis in a peristaltic flow of a variable viscosity fluid and reveal that entropy production is high in the contracted region and reduces in the wider part of channel. Some more interesting studies on the topic could be of interest for readers [13][14][15][16][17][18][19][20].…”
