Abstract
The equilibrium Aeolian sand transport is simulated by Lagrange gas-solid two-phase model. When the velocity and angle distribution of ejected grains are described by normal distribution function obtained by Nalpanis and Hunt in their experiment, the simulated profile of horizontal mass flux is inconsistent with the experimental profile. After detail analysis, we present a modified splash function in which the angle distribution of ejected grains is fitted by normal function and the velocity distribution is fitted by a segmented function comprised of exponential distribution and Gaussian distribution. The simulation result indicates that the modified splash function can well describe the nature of ejection phenomenon in equilibrium sediment transport.
