...Jin Yang; Tengjiao Lin This paper presents a novel fast calculation method for windage power loss (WPL) of the meshing double-helical gear pair. Firstly, based on the basic equations of fluid mechanics and computational fluid dynamics simulation method, the calculation method for single-tooth...

... losses of common combinations of two, three, and four bends and the addition of internal vanes were investigated with computational fluid dynamic simulations and validated with reference data. Pressure losses of combinations of bends without vanes were higher or lower than the sum of the single pressure...

... of the vehicle's longitudinal dynamic model in our recent work. The vehicle's accelerating and decelerating motions are simulated in the straight flight state using a self-developed numerical method based on the vehicle's dynamic model with the designed control law. Motion characteristics are analyzed...

.... A direct transient simulation of the problem of steam ingestion into a transonic rotor is computationally expensive. There was, however, one characteristic of the problem that allowed for its simplification. Relative to the rotor speed, the change in inlet gas properties was very gradual and therefore...

...Tabatabaei Hamidreza; Boroomand Masoud; Taeibi Rahni Mohammad Three-dimensional steady and unsteady (pulsating) compressible flows in a vane-less turbocharger turbine of a 1.7 liter SI engine are simulated numerically, and the results are validated experimentally using a turbocharged on-engine test...

..., as shown in Fig. 10 . In addition, the maximum velocity field for u 0  = 0.3, 0.8, and 1 m/s are 2.585, 2.703, and 2.848 m/s, respectively. In order to verify the accuracy of the present numerical model, the modified case of the simulated results is then validated against the experimental data...

... for one-dimensional flow, a mathematical model of the pneumatic pipe with lumped parameters was developed using ordinary differential equations, which can be easily implemented in most computer programs for the simulation of complex heterogeneous engineering systems. Implemented in Matlab-Simulink...

...Seok-Won Kang; Debjyoti Banerjee In this study we implemented the network simulation techniques using macromodels (lumped models) for capillary driven flows in microfluidic networks. The flow characteristics in a flow junction, such as meniscus stretching and bifurcation, were studied...

...Ali Benhmidene; Bechir Chaouachi; Mahmoud Bourouis; Slimane Gabsi In the present study, the ammonia-water mixing flow in a bubble pump is numerically simulated. The flow patterns of a two-phase flow in a bubble pump were studied under different conditions of heat flux and tube diameter. A one...
