A synoptic parameterization of the drag coefficient

Drag coefficient and strouhal number analysis of a rectangular probe in a two-phase cross flow

In some case of laboratory and industrial applications, various kind of measurement instruments must be placed in a conduit, in which multiphase fluid flows. Vortex shedding for any immersed body in flow field is created with a frequency, which according to flow conditions such as flow rates, geometry of body, etc. may be constant or variable. Failure may happen, if this frequency is close to o...

Self-Acceleration in the Parameterization of Orographic Gravity Wave Drag

A new effect related to the evaluation of momentum deposition in conventional parameterizations of orographic gravity wave drag (GWD) is considered. The effect takes the form of an adjustment to the basicstate wind about which steady-state wave solutions are constructed. The adjustment is conservative and follows from wave–mean flow theory associated with wave transience at the leading edge of ...

A New Correlation for Drag Coefficient of Extrudate Quadralobe Particles by CFD Simulation

Constraints on Wave Drag Parameterization Schemes for Simulating the Quasi -

Parameterization schemes for the drag due to atmospheric gravity waves are discussed and compared in the context of a simple one-dimensional model of the quasi-biennial oscillation (QBO). A number of fundamental issues are examined in detail, with the goal of providing a better understanding of the mechanism by which gravity wave drag can produce an equatorial zonal wind oscillation. The gravit...
