AI Technical Summary

Technical Problem

Existing fluid analysis methods struggle to accurately determine dynamic physical quantities, such as pressure, of gas-liquid mixtures due to the need to assume variables in the analytical model, particularly when bulk modulus is measured, leading to inaccuracies in pressure calculations.

Method used

A gas-liquid mixture fluid analysis method that incorporates the measured amounts of separated and dissolved gas, along with the times for gas dissolution and separation, as variables in the fundamental equation, to improve calculation accuracy.

Benefits of technology

Accurately calculates the physical quantities of gas-liquid mixtures, including pressure, by considering both visible and dissolved gas, enhancing the precision of fluid analysis.

Abstract

To provide a method for analyzing a gas-liquid mixture fluid that can calculate the physical quantity of a gas-liquid mixture fluid as accurately as possible when the physical quantity of the gas-liquid mixture fluid is calculated by fluid analysis means of an arithmetic processing unit.SOLUTION: When the dynamic physical quantity of a gas-liquid mixture fluid in which gas and liquid are present in a mixing state is calculated by fluid analysis means of an arithmetic processing unit 1, the quantity of gas which is in a separation state from the liquid in the gas-liquid mixture fluid and the quantity of gas which is dissolved in the liquid are measured, and the quantity of the separating gas and the quantity of the dissolved gas are used as variables of a basic equation of fluid analysis means so that the fluid analysis means calculates the dynamic physical amount of the gas-liquid mixture fluid.SELECTED DRAWING: Figure 3
