Abstract : The flow of thermoviscous fluid within the annulus of circular cylinders with a local constriction at the outer wall is investigated analytically, assuming that the constriction is nonsymmetric wrt the radial distance. Analytical solutions for velocity and temperature fields have been obtained. The effect of the shape parameter of the constriction on velocity, temperature, Nusselt number, and flow rate are illustrated graphically and discussed.
