Correct prediction of critical gas velocity at which the well starts to load is very important to the operators since they could take appropriate measures to prevent liquid loading and extend the well production life. In the past, most studies on liquid loading focused on vertical wells. Only ...

We express the investigated quantities in terms of the response function to temperature variations in the H model of Halperin, Hohenberg, and Siggia. Results are compared with the experimental data.关键词: Theoretical or Mathematical/ acoustic dispersion acoustic wave absorption acoustic wave velocity ...
The critical velocity increases with decreasing power-law index and follows an exponential trend with the equivalent particle size for a given value of the power-law index. The exponent showing the dependency of the critical velocity on the equivalent particle size changes linearly with the power-...
The Alfven "critical ionization velocity" (CIV) mechanism for the anomalously rapid ionization of a neutral cloud moving across a magnetized plasma at a supercritical velocity was proposed originally to explain the formation of the early solar system. Since then, many theoretical and experimental studi...
This rate depends not only on the temperature but also on the wind velocity and humidity. For example, at 20°C, air moving with a velocity of 30 cm/sec removes more heat than still air at 15°C. In this case, a mild wind at 30 cm/sec is equivalent to a temperature drop of ...
The critical flow velocity phenomenon is common in erosion-corrosion of many materials. It is of great importance to develop methods to determine the critical flow velocity and understand mechanisms of the phenomenon so that it can be used for proper applications. This paper provides a critical rev...
The critical anomaly of the isobaric molar heat capacity for the liquid-liquid phase transition in binary nonionic mixtures is explained through a theory based on the general assumption that their partition function can be exactly mapped into that of the Ising three-dimensional model. Under this app...
