Abstract:

THE OBJECTIVE OF THIS EFFORT IS TO ASSESS THE ACCURACY OF A RECENTLY DEVELOPED CODE, TURF2, TO PREDICT TRANSIENT EFFECTS CAUSED BY A SHOCK WAVE MOVING OVER A SAND BED, AND DIFFRACTING OVER AN OBSTACLE ON THE SURFACE AND IN A HOT LAYER OF GAS. DURING 1984, TURF2 TWO-PHASE FLOW BOUNDARY CONDITIONS AND TWO-PHASE FLOW TURBULENCE MODELING WERE IMPLEMENTED AND TESTED FOR STEADY FLOWS. RESULTS COMPARED WELL WITH EXPERIMENTS FOR FLOWS RESULTING FROM A WIND ABOVE A SAND BED AND FROM A SHOCK WAVE SWEEPING A SAND BED. IN THE PROPOSED EFFORT, A SERIES OF UNSTEADY TURBULENT TWO-PHASE FLOWS WILL BE SIMULATED AND COMPARED WITH EXPERIMENTAL DATA: (1) FOR A SHOCK WAVE SWEEPING A SAND BED, (2)FOR A SHOCK WAVE SWEEPING A SAND BED AND DIFFRACTING OVER AN OBSTACLE,(3) FOR A SHOCK WAVE SWEEPING A SAND BED INCLUDING A HOT LAYER OF GAS AND DIFFRACTING OVER AN OBSTACLE.
