Abstract: Most of the existing codes are using stress-block parameters which were derived for normal strength concrete. Several researchers in the past have reported that use of ACI 318 stress-block parameters results in un-conservative ...

Abstract: The analysis of the numerical study of underwater high-speed gas jets is presented in this study. This work aims to understand the development of the flow structure of the gas jets submerged in water and assess the performance ...

Abstract: Grid fins are unconventional control surfaces consisting of an outer frame supporting an inner grid of intersecting planar surfaces. Although afflicted with higher drag, these have been credited for their enhanced lifting ...

Abstract: Cavitating flows entail phase change and hence very large and steep density variations in the low pressure regions. These are also very sensitive to: (a) the formation and transport of vapor ...
