  Fibrous material is a complex porous medium and steady test methods are the main test approaches we currently depend on to study the heat transfer properties. The application of unsteady test methods on fibrous material is still not mature. In this paper, some systematic studies are taken to investigate this problem. The purpose of this experiment is to study some of the famous instruments used in flow measurements. Calculate the coefficient of discharge from experimental data for a venturi meter. Determine the relationship between Reynolds number and the coefficient of discharge. 2. INTRODUCTION.

Fluids Eng (April, ) The Design of a New Flow Meter for Pipes Based on the Drag Force Exerted on a Cylinder in Cross Flow (Drag Force Flow Meter: DFFM). Thermal Mass flow meters use the thermal properties of the fluid to measure the flow of a fluid flowing in a pipe or duct. In a typical thermal mass flow meter, a measured amount of heat is applied to the heater of the sensor. Some of this heat is lost to the flowing fluid. As flow increases, more heat is lost. The amount of heat lost.

This paper investigates the performance of a device that measures the time of flight of a heat pulse in a gas stream to determine the flow rate in a pipe. A fusion of the theoretical, experimental, and numerical data is used to suggest a gas-independent correlation function between the response time and flow by: 4.

Actually, many devices used for flow rate measurement in oil and gas fiscal metering like orifice and turbine meters are often employed. This work dea. The comparisons of theoretical and experimental results in Figs. 4 and 5 have seen to be in good agreement.

Implementation of digital signal processing techniques in the design of thermal pulse by: The pulse tube engine is a simple prime mover based on the pulse tube process.

It has high potential to be applicable in waste heat usage. In the present work a simulation model is used to design a pressurized experimental pulse tube engine employing helium as working fluid. The measured engine characteristics are compared with the calculated predictions.

A vacuum insulation panel (VIP) is an inorganic composite insulation panel with a thermal conductivity of almost W/(m•K) and a Class A fire resi. Using the model and the experimental test rig, the engine performance is studied for different heat input temperatures, filling pressures, and operating frequencies.

The energy conversion process, based on a broken thermodynamic symmetry and a thermal lag occurring in the pulse tube, is proven theoretically. The heat-pulse flowmeter (HPFM) used in this study consists of a wire-grid heating element and two sensitive thermistors (heat sensors) that are positioned above and below the wire grid.

The annulus between the measurement section of the probe and the borehole wall is sealed with a flexible rubber disk in order to force all of the borehole flow.

In the experimental range, the variation in discharge coefficient is less than 6%, which compares well with that of the V-cone flowmeter. For No. 1 perforated orifice with β =the relative variation in discharge coefficient is as low as % when the distance between the orifice and the disturbance is over 5 D.

The comparison of this flow-meter reading with the standard flow-meter indicates the existence of different calibration regimes, bifurcated by a sharp change in slope of the calibration curve.

I. Introduction. Piezoelectric polymer composites with 1–3 connectivity consist of length-extensional piezoelectric elements embedded in a passive matrix. The benefits of 1–3 piezocomposites are well-recognized for transducer imaging applications, taking advantages of the high electrome-chanical properties of piezoelectrics and low acoustic impedance of polymers.The characteristics of a thermo tube type thermal gas flowmeter were analyzed and experimental results were described.

The output of this flowmeter is temperature difference between two points along an electrically heated capillary. An analytical expression of its outputs was derived assuming a simple flow condition.
