Abstract The present study intends to improve the performance of the Ranque-Hilsch counter flow vortex tube, analysed using computational fluid dynamics. In the axisymmetric 3-D, steady-state, compressible, and turbulent flow vortex tube, the air has been used as the working fluid. The ANSYS17.1 FLUENT software has been used with the standard º-ε turbulent model for different mass fraction of cold fluid and inlet pressure in the numerical simulation and validated with the experimental results. It is observed from the study that as the inlet chambers number increases from 1 to 2, there is a decrease of 7.8 % in the cold exit temperature of the vortex tube. However, insulating the double chamber vortex tube leads to a further reduction of 4.2% in the cold exit temperature. Therefore, it indicates that the overall decline in the cold exit temperature from one chamber non-insulated vortex tube to double chamber insulated vortex tube is 9.6%. In terms of cold exit temperature, it can be concluded that using a double inlet chamber vortex tube with insulation yields the optimum results.

ABSTRACT The use of a continuous-flow vortex separator as a component of an oil spill clean-up system was investigated. Tangential injection of the oil-water mixture into the vortex tube produces buoyant forces which accelerate the lighter oil to the vortex axis. The cleansed water and the core containing the oil are exhausted through exit ports in opposite end walls of the vortex tube. The cleansed water would be returned to the sea and the core flow containing the oil would be stored. Tests of laboratory-scale model vortex separators were made using oil-water mixtures having inlet oil-to-total-flow ratios between 0.002 and 0.3 and for a variety of geometric and flow conditions. The tests were made using four types of oil (napthene-base crude, paraffin-base crude, diesel and No. 6 heating fuel) having viscosities between 3 and 4250 cps (measured at 75 F) and specific gravities between 0.83 and 0.97. The results showed that separator performance may be optimized by proper control of the oil exhaust flow. Under optimum conditions, approximately 90 percent of the injected oil was separated and captured, and the captured flow contained approximately 90 percent oil. Studies were also made to determine the sizes and weights of components for full-scale vortex separators, including the necessary pumps and prime movers.

The change in air temperature along the axis of the expansion chamber in the zones of the nozzle inlet and the flow swirler in the direct-flow, counter-flow, three-flow and single-flow vortex tubes has been investigated. It has been established that in all cases, the cooling of air in the vortex tube occurs in the zone of the swirling device, and its heating - in the zone of unwinding of the flow. The change in air temperature in the axial zone along the length of the expansion chamber occurs due to heat exchange between the heating and cooling zones.
