a sand slide model is suggested in order to smoothen out numerical instabilities that occurs when the predicted slope of the scour hole exceeding the angle of repose of the sediment.
其中,通过改进沙滑模型以修正当生成的剖面坡度超过泥沙休止角时造成的模拟失真,同时克服数值计算的不稳定性。
the paper takes the determination of the material on belt as an example to show that the angle of repose of bulk solids on the belt depends upon bulk solids mechanics.
本文以货流断面积的计算问题为例,说明以松散物料力学为依据确定运输带上的安息角。
the angle of repose and compressibility were used to investigate the flowability of powder.
以休止角及压缩度来评价粉体的流动性;
and by using the wedge accumulation model, a formula for calculating the angle of repose of symmetrical dispersed sediment is deduced ;
运用散体沙的楔入堆积模型,推导散体沙的水下休止角计算公式,并结合干容重计算公式,计算散体沙的水下休止角。
