| Summary: | Based on the physical model of the Ranque effect, proposed earlier, a simplified mathematical model of
the working process of a vortex tube is compiled taking into account the exchange of work and heat
during the interaction of peripheral and axial gas flows.
The effect of viscosity and angular velocity gradient on the transfer of kinetic energy from the axis
to the periphery is shown. The difference in thermodynamic temperatures when heat is supplied from
the periphery to the axis is taken into account, which leads to a decrease in the cooling efficiency
of the axial gas flow. Energy exchange is based on the assumption that the peripheral gas layers are
compressed by the axial flow. The axial flow work is determined by the pressure difference between
the valve and the outlet of the diaphragm |
