This paper provides a computer program which is used to account the pressure change inside of the train which is isolated each other based on the flow rate coming in and out of sealed car,and simulates the inside pressure changes of trains with the.

Chaotic analysis of pressure fluctuations in impinging region of SCISR;

Simulation experiment on oil recovery mechanism in pressure fluctuation;

Hurst's analysis of pressure fluctuation in gas-solid spouted beds;

Periodicity analysis of pressure fluctuations in the impinging entrained-flow gasifier;

Characteristics of differential pressure fluctuations in vertical upward gas liquid solid three phase flow under the condition of normal temperature and normal pressure were studied by using the signal process techniques.

Many authors randomly chose different compact support Daubechies wavelet to analyze pressure fluctuations in fluidized beds.

In this paper,an accurate model predicting steady surge pressure resulting from running or pulling a pipe in a vertical wellbore has been developed on thebasis of Herschel-Bulkle.

5 mm casing,formation fracture pressure and well bore surge pressure in horizental wellbore designs are studied,and a conclusion is drawn that the key factor of horizental wellbore designs is to determinate the set depth of φ244.

Calculation method of surge pressure caused by mud viscosity during drilling pipes or casings moving through Cas.
