Abstract: The effect of free stream turbulence on the characteristics of a turbulent wake developed from the trailing edge of a thin and smooth flat plate was studied analytically and experimentally. ...

Abstract: A critical assessment is made of several different approaches that can be used for modeling near-source diffusion in weak winds, including the calm condition. For the convective boundary layer, the statistical theory ...

Abstract: Errors associated with the linear and the logarithmic finite-difference approximations of gradients in the surface layer are computed using the well-known Monin-Obukhov flux-profile relations. It is shown that while the ...

Abstract: The majority of twist drills used in orthopaedics are very similar to chisel pointed metal drilling bits. Modifications usually observed are reduction of the point angle to 90 deg and sometimes ...

Abstract: The vertical diffusion of a passive tracer released from surface and elevated sources in a neutrally stratified boundary layer has been studied by comparing field and laboratory experiments with a non-Gaussian K-theory ...

Abstract: An extensive and systematic water-tank study was performed to simulate the urban heat island under a calm and stably stratified environment. The objective was to examine the mean-temperature field, mixing height, and ...

Abstract: A fully turbulent, low-aspect-ratio buoyant plume with no initial momentum under calm and stably stratified conditions is produced in a convection tank. The plume is generated by a circular heat island at the bottom of the ...
