This thesis is a computational analysis of the incompressible laminar boundary layer on a continuous moving surface. The skin friction and heat transfer variations on a moving plate with similar and non-similar (constant) mass transfer at the wall are obtained for 210 cases for the similar boundary solution and 60 cases for the non-similar solution.
Both cases were solved numerically using the fourth order Runge-Kutta algorithm. For the non-similarity case, the local non-similarity method as described by Sparrow, Quack and Boerner was used. The analysis shows that the shear stress for both the similar and non-similar cases is higher when the velocity of the wall is greater than the free stream velocity. It decays with increasing mass transfer at the wall. The shear stress also increases as the velocity difference is enlarged.
Analysis was also made to determine the heat transfer from the plate for the similar boundary layer cases. The results of the analysis show that heat transfer is greatest when the wall velocity equals the free stream velocity. Also, heat transfer was enhanced by increasing the injection parameter and decays with increasing velocity difference. Practical applications of this flow field are extrusion of porous plastic sheets, quenching of large perforated metallic sheets, and water condensing on aircraft during flight. Water condensation during flight is of interest in the problem of aircraft icing.
