RT Journal Article ID 782dfafc29eac629 A1 Abdel-Fattah, A. T1 Effect of Inlet Flow Angle on the Flow Characteristics in Chamber JF International Journal of Fluid Mechanics Research JO FMR YR 2011 FD 2011-05-04 VO 38 IS 1 SP 56 OP 70 AB In the present study, a steady laminar and incompressible fluid flow issues from wall injection in a circular chamber has been studied experimentally and numerically. The water is injected from injection system into the chamber through the wall jets. The static pressure variation along the chamber length is measured and calculated for different values of Reynolds numbers and inlet flow angles. The average heat transfer variation with Reynolds number has been obtained for different values of the inlet flow angle. The velocity vectors, velocities and temperature contours are found. The flow Reynolds number in this study is found to vary between 433 and 910 at inlet flow angle of 0,15, 30, 45 and 60°. The results indicate that the pressure recovery coefficient decreases as both Reynolds number and inlet flow angle increase. The average heat transfer coefficient increases with increasing both Reynolds number and inlet flow angle. Numerically, the results showed that two recirculation zones occur in the sides of center line of the chamber behind the step. The size of these recirculation zones increases by increasing Reynolds number. As Reynolds number increase, the flow temperature decreases in down stream direction.
