The adiabatic compressibility, variation of specific volume with temperature and the specific heat at constant pressure have been measured for 24 liquids after careful purification. The isothermal compressibility and the ratio of specific heats are obtained in each case by calculation. A comparison is ...

The blocks in the Isothermal Liquid library account for density as a function of pressure, and pipe and actuator blocks account for compressibility by default. As a result, expect some differences between a model that uses Hydraulics (Isothermal) library blocks and a converted model when compressibi...
Reduced Volumetric Expansion and Isothermal Compressibility Factor PlotsThe volumetric expansion coefficient ( ln V / T ) p has been found useful in heat-transfer analyses. Yaskin et al . [ 1 ] demonstrated its usefulness in groupie hehum heat-transfer data in the near-thermodynamic critical ...
The theory takes account of wall friction, compressibility and flow choking. A set of working formulas is obtained. In the second part, results of experiments on homogeneous bubbly flows of water-air mixtures in a 1-in. Pipe are reported. Criteria for the occurrence of bubbly flow are ...
To calculate the pressure drop, the calculator performs friction factor f and minor resistance coefficient K calculation, as well as the mean velocity of the flow on the pipe start and the pipe end. The calculator includes Reynolds number (Re) calculation, as well as compressibility factor (Z...
These studies also focus on compressibility effects [18], [19]. Generically, there are many difficulties in finding accurate turbulent models since the details of the experimental data are not well known. In addition, the thermal flow conditions may not be well posed in the geometry (see Ref....
2) Isothermal equation of state 等温状态方程 1. According to the characteristics of liquid compressibility,a new isothermal equation of state is proposed which can be used to calculate the volume of liquids at differant pressures V= (A/(P+C)~n),where V is the volume,P is the pressure,...
(Isothermal) library blocks and a converted model when compressibility effects play a significant role due to the treatment of conservation equations in the volumetric-flow-rate-based and mass-flow-rate-based libraries. An example of this is provided inConversion When Fluid Dynamic ...
The air tests were carried out over a range of Reynolds numbers to establish the effect of compressibility on the pressure drop loss coefficients. Water tests were undertaken to check the validity of the results and of the proposed calculating method. (Author)...
