Three-dimensional turbulent bistable flow (TBF) in an open-channel expansion is predicted using large eddy simulation. The free surface of TBF tracked the volume fluid method, coupled with level-set method. This paper aims to reveal ensemble-average characteristics and explore effective ways control bistability. For a given condition approaching expansion, either two stable states can possibly ...

theory, when appropriate allowances are made for the noisy freestream and the nonlinear disturbances not identified by the linear theories. It remains to be determined if the incompatibility of planar boundary-layer instability phenomena with classical linear stability theory is a unique feature of the planar boundary layer or if it is a noisy wind-tunnel characteristic that affects planar boun...

The efficiency of three different biosensor flow cells is reported. All three flow cells featured a central channel that expands in the vicinity of the sensing element to provide the same diameter active region, but the rate of channel expansion and contraction varied between the designs. For each cell the rate at which the analyte concentration in the sensor chamber responds to a change in the...

The renal vascular and functional responses to acute volume expansion were determined in conscious dogs with all reflexes intact, sinoaortic arterial baroreceptor denervation, arterial baroreceptor denervation plus bilateral stellectomy, and arterial baroreceptor denervation plus bilateral vagotomy. In the intact dogs, when an isotonic saline infusion increased right atrial pressure by 6 mm Hg,...
