107, pp. 279289, in 2002 to simulate the microchannel and microcavity flows in the transitional flow regime. The present article intends to test the feasibility of doing so. The results of using the lattice Boltzmann method and the direct simulation Monte Carlo method show good agreement between...
These vehicles which are increasingly being used for reconnaissance purposes operate in the Root Chord Reynolds number range of 104 to around 105 and thus, the flow regime encountered is in the low Reynolds number transitional flow range. Computational Fluid Dynamics (CFD) methods which employ eddy...

This paper presents a computational fluid dynamics (CFD) methodology to accurately predict the heat transfer characteristics of an unconfined steady impinging air jet in the transitional flow regime, impinging on a planar constant-temperature surface. The CFD methodology is validated using detailed experim...
It has been reported in the literature that most boundary layer flows in turbomachines include a transitional flow regime unless they are tripped at the leading edge of the blade. In the past, the boundary layer prediction for turbomachinery blades frequently ignored the transition region and conside...
In the transonic flow regime, wings with high sweep are commonly affected by transition caused by crossflow (CF) vortices. Two types of CF instabilities exist: stationary CF vortices and traveling CF waves. From the physical point of view, these two different families of modes are generated by...
Integral method of steam-water flow description is used (two-velocities). Theoretical basis for calculation of flow parameters of transitional regime is developed. Criterions of this regime existence are determined. 会议名称: Proceedings Twenty-Ninth Workshop Geothermal Reservoir Engineering, Includes: ...
The present contribution extends the DNS simulation into the turbulent flow regime, to a rotational Reynolds number Re =3 × 10 5 . An annular rotor-stator cavity of radial extension Δ R and height H , is considered with L = 4.72( L = Δ R / H ) and Rm = 2.33 ( Rm = ( R 1...
As everyone knows who has opened a kitchen faucet, pipe flow is laminar at low flow velocities and turbulent at high flow velocities. At intermediate velocities, there is a transition wherein plugs of laminar flow alternate along the pipe with "flashes" of a type of fluctuating, nonlaminar fl...
