Study of a submerged real-gas jet

Numerical modelling of three-dimensional fluid flow in a spiral compensator

“…The term − | v| v/(2D) in ( 4) takes into account the losses due to wall friction in channel. A number of different computational formulas for the wall friction number were proposed by Abramovich (1991) for the case of a stationary flow as functions of the Reynolds number and the relative wall roughness. Because of the periodic shock waves the flow in a spiral rectangular channel is strongly nonstationary.…”

Modeling the evolution of the aerosol cloud of toxicants in the atmosphere

“…The physical properties of air due to vertical coordinate of account for a specific date using the parameters of the standard atmosphere and the data of weather stations was taken on. The coefficient of dynamic viscosity of air using the Sutherland formula [15] was calculated:…”

Length of the separation zone behind an unstreamlined body in a restricted stream

“…

The effect of channel obstruction on the length of the circulation zone behind bodies of the projection-type in a restricted turbulent stream has been studied experimentally and the results are analyzed here.One problem in the design of combustion chambers for gas turbines is to ensure a stable combustion of fuel during all modes of plant operation.The most widespread method of stabilizing a flame is based on the laws of fluid flow in the immediate trail behind an unstreamlined body. It must be emphasized that the use of unstreamlined bodies for flame stabilization, which until now has been limited to blended fuel mixtures only, is since recently found more often in the design of stationary gas turbines with a diffusive combustion process in so-called jet stabilizers [1],Many studies have been made concerning the kinematics of flow and the structure of the separation zone in a turbulent fluid behind unstreamlined bodies of various shapes [2][3][4][5][6].

“…1, without both the transition stage of the jet and the boundary layer developing at the surface of the unstreamlined body. A kinematically analogous pattern prevails around flat and axiosymmetric half-solids [2,3,15,6], stairs [6], closed cavities [17], and twin projections [12,18].
