Considering the electric field aberration in the interelectrode gap caused by the particles, the influence of the particles on the discharge gap and the dielectric constant of the working fluid is calculated utilizing the "Wagner Model".

R-113 was used as the working fluid. The results indicated that there was a 11-80% increase of heat transfer coefficients for falling film boiling on the enhanced lubes in comparison with those of their pool boiling; and there was a 2.7-6.2 times increase in comparison with those for falling film boiling on a smooth tube.

An experimental study has been first carried out to systematically investigate the effects of the distance, orientation and intensity of acoustic cavitation field and fluid subcooling on boiling heat transfer from horizontal circular tube, using acetone as the working fluid, and the primary mechanisms have been analyzed.

There are two operation phases for the loop:1) in the first phase, the loop would be operated for MHD effects studies using the working fluid of sodium-potassium eutectic alloy( 22 Na 78 K), with maximum Hartmann number( M ) of 0.75×10 4 and interaction parameter( N ) of 2.5×10 4 during this period;

A mathematical simulation was provided. R134a was taken as the working fluid. The temperature of the generator, condenser and evaporator was 90℃ ,20-38℃ and 6-14℃, respectively.

Taking the analysis results as the basis of designing for reasonable adiabatic structure,a heat insulation with thickness of 100mm is designed inside the valve body,it was successfully solved the problem that the requirement of the temperature on outer of valve body should less than 100℃ when the valve is operating at the pressure of 8MPa and the working fluid's temperature is higher than 627℃.

On restart, the spalled material may lodge somewhere in the system with the potential for causing tube blockages, or it may be swept out with the working fluid and enter the steam turbine causing erosion damage to the turbine nozzles and blades.

It is proposed to assess the energy efficiency of cogeneration systems in terms of the energy lost with the working fluid, Δq.

Process modeling offers a fairly simple means of determining the effect of the key parameters of the material being pressed and the working fluid on the rate of pressure rise in the press-container system.

We consider the theoretical aspects of measurement of the counted contaminant concentration in the working fluid and problems connected with quantitative assessment of the efficiency of the proposed device.

It is shown that the use of water-soluble solid polymer solutions as the working fluid in the generator of the pulsating jet leads to an increase in the depth of the holes and grooves by a factor of 1.5-3.5.

On the basis of a 1.5m2 flat-plate intermittent solar ice maker, a 8m2 flat-plate automatic following continuous solar refrigerated locker is built and studied, and is served as the foundation for further study of an air-conditioning system. Two pairs of photo-electric cells are used for controlling the azimuth and inclination of the collector.

On the basis of a 1.5m2 flat-plate intermittent solar ice maker, a 8m2 flat-plate automatic following continuous solar refrigerated locker is built and studied, and is served as the foundation for further study of an air-conditioning system. Two pairs of photo-electric cells are used for controlling the azimuth and inclination of the collector. For the purpose of using various energy sources, the collector tubes are still made of casing pipes. The work fluid is ammoniawater solution, the direction of strong and weak solutions flowing to and from the collector is tested, and the elimination of rectifying column is again attempted. The performance of the evaporator-refrigerated locker is evaluated.

In this paper, the author points out that there exist two different conditions of suppling low temperature heat. One is the unvariance of mass rate of the hot fluid, and another is the unvariance of amount of the suppling heat. From the thermoeconomic respect, these two conditions demand the working fluids differently or even contrarily in some thermophysical properties.Then, from the thermodynamic theory and the characteristics of electric generation from low temperature heat, the author has derived...

In this paper, the author points out that there exist two different conditions of suppling low temperature heat. One is the unvariance of mass rate of the hot fluid, and another is the unvariance of amount of the suppling heat. From the thermoeconomic respect, these two conditions demand the working fluids differently or even contrarily in some thermophysical properties.Then, from the thermodynamic theory and the characteristics of electric generation from low temperature heat, the author has derived four formulas for calculating the optimal temperatures of vaporization and condensation of working fluids and other four formulas for calculating the correcting coefficients.Through a large amount of calculations for various working fluids and various parameters, these formulas are proved to be reliable and accurate. These formulas will serve as a convenient means for the thermodynamic calculations in designing power plant of low temperature heat, and a great deal of time spent on these calculations will be saved.
