On Unsteady Flow of a Dissociating Gas
Defence Science Journal, 1981 Lighthill's model of an ideal dissociating gas has been exploited to study three dimensional unsteady flows in the absence of dissipative mechanisms. Expressions for the tangent, principal normal and binormal vectors, curvature and torsion of streamlines, variations of pressure along streamlines and their principal normal and binormal have been ...

Energy Science &Engineering, EarlyView.Turbulence intensity from 1% to 25% was parametrically tested on a three‐bladed H‐type Darrieus rotor across five tip speed ratios (TSRs) using two‐dimensional URANS. The optimal TSR proved the most efficient and most robust operating point simultaneously, with Cp losses capped at 5.8% even at TI = 25%. ABSTRACT The effect of inlet turbulence intensity

Energy Science &Engineering, EarlyView.Variable‐rate hydraulic fracturing can induce unsteady flow in the tubing, thereby generating fluctuating fluid pressure near the bottom‐hole reservoir. Dynamic stress is generated in the reservoir under the action of fluctuating fluid pressure and propagates as stress waves.
