Autor: null Ghassan Nasif, null Yasser El-Okda, null Mouza Alzaabi, null Habiba Almohsen

Publikováno v: CFD Letters. 14:18-30

A numerical study using the conjugate heat transfer approach has been performed to investigate the effects of boundary heat flux, conduction effect, and working fluid on the thermal characteristics due to the jet impingement process. Air and water ar

Secondary Currents at Very Low and High Aspect Ratios of Open Channels

Autor: null Monsif Shinneeb, null Ghassan Nasif, null Ram Balachandar

Publikováno v: CFD Letters. 14:1-15

The present numerical study is an attempt to better understand the effect of the aspect ratio (AR) on the velocity field characteristics of the fully-developed turbulent flow in a straight open channel by contrasting a very low and very high aspect r

Turbulent Structures in Gap Flow

Autor: null Ghassan Nasif, null A.-M. Shinneeb, null Ram Balachandarandar, null Chandra Somayaji

Publikováno v: CFD Letters. 14:24-34

A computational study was carried out to investigate the effect of the gap between the body and the bed on the wake characteristics in shallow flows. A sharp-edged bluff body with two different clearances from the bed is employed in this investigatio

Effect of the aspect ratio on the velocity field of a straight open-channel flow

Autor: Ghassan Nasif, Ram Balachandar, A.-M. Shinneeb

Publikováno v: Physics of Fluids. 33:085110

This study investigates numerically the effect of the aspect ratio (AR) on the velocity field characteristics of the turbulent flow of a straight open-channel flow. Five aspect ratio cases (AR = channel width/flow depth) are investigated ranging from
