To broaden the range of known circulations and to test existing theory, a variety of issues are examined concerning the dynamics of flows in thick, thin, and transitional atmospheric layers. The circulations are produced numerically using a primitive equation model subject to simple heating functions. To confine the motions to a thin upper layer, the heating is chosen to produce a flow with eit...

Splattering of droplets during liquid jet impingement on solid targets alters the efficiencies of jet impingement heat transfer processes and chemical containment safety devices, and leads to problems of aerosol formation in jet impingement cleaning processes. A study of the turbulent liquid jet impingement splattering, the evolution of the disturbances on the free surface of a turbulent liquid...

A CFD study on heat flux reduction in hypersonic flow with opposing jet has been conducted. Flowfield parameters, reattachment point position, surface pressure distributions and heat flux distributions are obtained and validated with experiments. The physical mechanism of heat reduction has been analyzed. When the opposing jet blows, the freestream is blocked off, flows to the edges and not int...

SUMMARY An experiment designed to measure the external drag of fuselage side intakes is described. The scope of the experiment and the techniques employed are discussed and an assessment is made of the accuracy of results. Measurements of the external drag of rectangular intakes installed on the sides of a fuselage are presented. Results at subsonic speeds show that drag at full flow is indepen...

Fairness is the significant factor to sustain best effort delivery of network services. Now-a-days, real-time multimedia applications have evolved largely over the Internet. Most of multimedia services are unresponsive during network congestion. Unresponsive traffic streams steal most network bandwidth and starve out some other flows which are responsive during network congestion. In the presen...

There has been a worldwide interest to develop supersonic business jet (SSBJ) for minimum range of 4000 nm with low sonic boom intensity and high fuel efficiency. An SSBJ design model is developed in the GENUS aircraft conceptual environment. With model, low-boom low-drag concept designed optimized. This article studies its operational performances. The sustained cruise flight studied find out ...

The photon drag effect of a 2D electron gas is measured using the ps infrared pulses of the wavelength-tunable free electron laser source FELIX. The pulsed photon drag response is found to depend critically on the coupling characteristics of the electrical circuit. We therefore developed an impedance and velocity matched photon drag detector. It consists of a GaAs/ AlGaAs multi quantum well sam...
