Based on analysis of problems existed in application of inertial vibrosieve,the new type variable frequency hydraulic straight-vibrating sieve is introduced.
The calculations agree well with experimental results, which indicates that the model is instructive on the optimization of the dimension of inertance tube in Stirling type pulse tube cooler. 3.
The horizontal nonhomogeneity of the background wind and pressure fields influences the term of the inertial force in the motion equation and the wind speed at the upper boundary of the PBL.
