TLDR
In this paper, two different boundary conditions for the spin are considered: vanishing spin and vanishing surface moment, and the equations of motion are reduced to dimensionless forms which include three dimensionless parameters, and integrated numerically by a Runge-Kutta method.Abstract:
Plane and axially symmetric flows of a micropolar fluid, in contact with an infinite plate, and tending to potential flow at infinity, with a stagnation point on the plate, are considered Two different boundary conditions for the spin are considered: (a), vanishing spin; and (b), vanishing surface moment The equations of motion are reduced to dimensionless forms which include three dimensionless parameters, and integrated numerically by a Runge—Kutta method Results are presented both in tabular and graphical form, and the effects of the values of the parameters on the flow are discussedread more

Melting heat transfer in boundary layer stagnation-point flow towards a stretching/shrinking sheet in a micropolar fluid
TL;DR: In this paper, a mathematical model was developed to study the heat transfer characteristics occurring during the melting process due to a stretching/shrinking sheet, and the transformed non-linear ordinary differential equations governing the flow were solved numerically by the Runge-Kutta-Fehlberg method with shooting technique.

A similarity solution for the boundary layer flow of a polar fluid
TL;DR: In chemical engineering one often encounters fluids with complicated structures, eg suspensions, emulsions, solutions of high polymers etc It seems as mentioned in this paper, and this is the case in the field of chemical engineering.
