TL;DR: In this paper, the effects of both the fluid shear and rotational speed of a rotating rigid sphere on the drag and lift forces are estimated for particle Reynolds numbers of 1[les]Rep[les ]500.

TL;DR: In this paper, the effects of ambient pressure, initial gas temperature and combustion reaction on the evaporation of a single fuel droplet and multiple fuel droplets are investigated by means of three-dimensional numerical simulation.

TL;DR: In this article, a two-step global reaction scheme for coal is proposed, and the unsteady coal particle and combustion behaviors in a turbulent pulverized coal jet flame are investigated by performing a direct numerical simulation (DNS) employing the proposed global reaction schemes.

TL;DR: In this paper, a new model for the roughness length and drag coefficient was proposed for predicting momentum transfer across the sea surface under both normal and strong wind conditions using the universal relationship between energy and significant frequency of wind waves normalized by the rough length, which can be given against U10 only from the measurements of the wave parameters and one point mean air velocity in the logarithmic law region.

TL;DR: In this article, a new model is developed, assuming that the damping of turbulence near the surface can be represented by that of the surface wave motion with a wave length equal to the integral scale of turbulence.
