摘要：

An entropy generation analysis of steady boundary layer flow of viscous fluid with variable properties over an exponentially stretching sheet is presented. The basic nonlinear partial differential equations that govern the flow are reduced to ordinary differential equations by using appropriate transformations. Numerical solutions are obtained by using shooting technique along with Runge-Kutta method. Expressions for the dimensionless volumetric entropy generation rate (N-G) thorn and Bejan number are also obtained. The effects of different dimensionless emerging parameters on entropy generation number (N-G) and Bejan number oBethorn are investigated graphically in detail.
