Thermal Landau jet

Abstract

The author considers the steady-state temperature distribution in a jet of incompressible fluid emitted in pulsed bursts from a point source, with and without account taken of viscous dissipation. When viscous dissipation is not taken into account, an exact solution is obtained for the energy equation, bounded in the entire closed interval 0 ≤ θ ≤ π. When viscous dissipation is considered, the energy equation is obtained using the introduced separation of variables.
