Experimental study of unsteady heat transfer from a gas-suspension flow in the initial section of a cylindrical channel

Data are presented from experimental studies of unsteady heat transfer from a gas-suspension flow in a short cylindrical channel with an increase in the thermal load over time.Translated from Inzhenerno-Fizicheskii Zhurnal, Vol. 42, No. 6, pp. 885–892, June, 1982.     

Kinematic,integral, and thermal characteristics of turbulent stream of gaseous suspension under nonsteady thermal conditions

Estimating Diaphragm Flow Coefficients for Nonstationary Gas Flow

A diaphragm is the most common flowmetering device on major pipelines, on which one often encounters flow-rate pulsations, which destabilize measurements. An experimental check on numerical calculations shows that the metrological characteristics of an orifice meter in unsteady flow can be determined by numerical simulation from full-scale experiments.     

Construction of algorithm for calculation of the flow rate of a gas–liquid mixture in a horizontal pipeline for the microprocessor of an information measurement system

Features of an algorithm for calculation of the flow rate of the liquid phase of a gas–liquid mixture with the use of a variable pressure-drop flow meter with constricting devices are considered. Corresponding dependences for use in calculating the concentration of liquid in a mixture and a correction factor based on the readings of the flow meter for use in determining the flow rate of a single-phase flow are obtained.
