| Abstract | ||||
| The target of this research is to study theoretically and experimentally the performance of spot cooling of a tractor cabinet including a single internal heat source (tested body) by using vortex tube. In the theoretical study, the cabinet is cooled from the roof by one port and constant wall temperature for lower and side walls. The effect of inlet and outlet air ports position in the cabinet is considered. Moreover, the influence of varing the inlet cold air velocity to cabinet from 2.7o 12.5 m/s inlet cold air temperature to cabinet (rom 282.1 to 29’7.3 K, inlet air pressure to vortex tube from 1 to 6 bar, cold fraction of vortex tube from 29.6 to 78.9 and the Archimedes number from 12.55 to 617.84 in tube presence of a heat source with a constant heatflux of 120 W/m2 is abo studied. In this work, FLUENT 6.3.26 package is used ill Numerical study. The package solved the steady 2-D compressible viscous now. Various spot cooling geometries are applied. Specific conditions for each case are defined, and the computational fluid dynamics is provided for three different groups. Twelve cases of local inlet and outlet ports. The calculations au performed for ventilation effectiveness factor (VEF) which is ranging from 0.58 to 1.29. The best position for the Inlet locations is found in the up right of roof and the outlet locations in the up of left side. To validate the ideal case, an experimental test rig has been designed and constructed with the actual dimensions of the tractor cabinet. The expermints are aimed out with the same conditions the of ideal case. The comparison of the experimental data for that of the best position of the inlet port with the theoretical results gives a satisfactory agreement. | ||||
