Ultrasonic flowmeter is one of the most widely used devices in flow measurement. Traditional bulk piezoelectric ceramic transducers restrict their application to small pipe diameters. In this paper, we propose an ultrasonic gas flowmeter based on a PZT piezoelectric micromachined ultrasonic transducer (PMUT) array. Two PMUT arrays with a resonant frequency of 125 kHz are used as the sensitive elements of the ultrasonic gas flowmeter to realize alternate transmission and reception of ultrasonic signals. The sensor contains 5 × 5 circular elements with a size of 3.7 × 3.7 mm2. An FPGA with a resolution of ns is used to process the received signal, and a flow system with overlapping acoustic paths and flow paths is designed. Compared with traditional measurement methods, the sensitivity is greatly improved. The flow system achieves high-precision measurement of gas flow in a 20 mm pipe diameter. The flow measurement range is 0.5–7 m/s and the relative error of correction is within 4%.

“…Two-phase flow in tubes, equipments and channels is encountered frequently in industries and being researched for many years. Power generation, food production, nuclear technology, chemical industries etc., use two-phase flow [1]. The two-phase phenomenon is also used to provide fresh water through thermal desalination techniques.…”

The prediction of the frictional pressure drop in the two-phase flow has become highly crucial for the enhancement of heat transfer methodologies for various industrial applications in order to design thermal equipment efficiently. The pressure drop in the heat transfer equipment is affected by the system pressure, system geometry and working fluid. There is a dearth of literature on two-phase pressure drop in the conventional adiabatic tubes at subatmospheric system pressures. Experimental investigations on the pressure drop have been conducted at 0.25, 0.5, 0.75, and 1 bar system pressures in 1500 mm long, 8, 13.7, and 18 mm diameter adiabatic tubes. The steam at 0 – 1 vapor quality is used at 32 – 660 kg/m2s mass flux in the adiabatic tubes. The effects of tube diameter, vapor quality, mass flux and system pressure on two-phase frictional pressure drop are investigated. In the liquid-vapor flow, the pressure drop experiences a non-linear increase with changes in vapor quality. The frictional pressure drop in two-phase flow is elevated with higher vapor quality, reduced subatmospheric system pressure, increased mass flux, and a smaller tube diameter. The correlations suggested for two-phase frictional pressure drop at higher system pressure predict the pressure drop reasonably in the adiabatic tubes at subatmospheric system pressure.
