The water surface level, velocity field and sediment concentration field of gravel sand bed and sand bed reach on Jianjiang river were refined simulated.
The quantitative relation among the threshold wind velocity of sand movement, sand diameter and the agglutinate stress of sand bed is obtained with the mentioned dimensionless variables.
Discussion on the construction technology of borehole pile in the sand bed
The study shows that (1) porous dissipation of wave energy may be neglected on sand bed;
By modeling the form of water between sand particles in wet sand bed, the correlation among agglutinate stress, water content and sand diameter is set up. Accordingly, a discriminant of threshold condition of sand movement on wet sand bed is sought out.
S-wave section favours the disco- vering of minor faults and small structures, and the tracing of thin sand bed.
Prediction and experiment for α wave equilibrium sand bed height in horizontal well gravel-packing based on equilibrium velocity
It was getting dark. Fish shrimp are Busy drilling rock crevices, algae bushes, the sand bed. But the small sea ghost Bodi still swimming in four.
The two-phase flow over sand bed and in straight pipe is calculated. Two distinct distributions of particle concentration are found and analyzed.
