This work considers the well-known laminar boundary layer flows; about a flat-plate in
a uniform stream of fluid (Blasius flow) and about a moving plate in a quiescent am�bient fluid (Sakiadis flow) both under a convective surface boundary condition. Entropy
generation due to the effect of angle of inclination, magnetic parameter, chemical reaction
parameter and Schmidt number on the flows is investigated. The third order partial dif�ferential equations governing the flows are reduced to ordinary differential equations by
suitable similarity variables. The obtained equations are tackled by the Runge-Kutta fourth
order method with shooting technique and the results are employed to calculate entropy
generation. The solution of Blasius flow is compared with the works in literature and are
found to be in excellent agreement. Entropy generation can be minimized by increasing
the magnetic parameter (M), chemical reaction parameter (R) and Schmidt number (Sc)
for Blasius flow. Magnetic parameter reduces entropy generation for Sakiadis flow while
other parameters such as angle of inclination, chemical reaction parameter and Schmidt
number boost fluid irreversibility
