The filling of a horizontal hydrogen tank designed for light duty vehicles is investigated by means multi-physics numerical simulations. simulation approach, implemented in OpenFOAM, includes compressible Reynolds-Averaged Navier-Stokes (RANS) modeling the fluid flow and heat transfer solid parts. simulations are carried out 2D-axisymmetric 3D configurations. Two scenarios tank, leading to two ...

The possibility of a significant flight range extension guided aerial bomb during climb bombing due to the jet thrust created by solid-propellant rocket engine was considered. By means simulation, comparative analysis equipped (not equipped) with under typical conditions carrier aircraft level and performed. It demonstrated that use engine, whose mass is 20 % bomb’s mass, allows increase horizo...

The performances of ventilation in the buildings with quadrate and cylindrical cross-sections are compared numerically. incoming jet unsheltered-building is more horizontal comparison to unsheltered-building. dimensionless volume flow rates unsheltered-buildings respectively 0.503 0.553. sheltered-buildings flows floors immediately. velocity near floor sheltered-building greater than that shelt...
