Heat transfer by laminar flow of a third grade fluid in wire coating analysis with temperature dependent and independent viscosity

The flow of a third grade fluid in between the continuum (wire) and conical die is considered for wire coating analysis. The analysis is based on perturbation technique. The Reynolds’s and Vogel’s model are accounted for the temperature dependent viscosity. The influence of Reynolds’s model parameter m and Vogel’s model parameters, α and B is investigated carefully on solution of the problem. It is investigated that the velocity profile oscillates about r for the case of temperature dependent viscosity for the parameters m, α, β and B.
