The optimum working fluids to run the cycles are selected (water and R245fa).
On the other hand, the ejector performance is very sensitive to θ especially near the optimum working point.
Not only did such bacterial dose not enhance yields in fields FC, C and Corg, but it suppressed yield enhancement in field L (data not shown) in agreement with previous estimates of the optimum working bacterial dose36.
Optimum working fluids and thermodynamic parameters are those which simultaneously allow high cycle efficiency and high heat recovery from the heat source to be obtained.
The refrigerating performance of PTR was observed and the lowest no-load temperature of 70.4 K was obtained at its optimum working frequency 5.6 Hz.
However, at present model on the system part-load behavior is lacked and the optimum working condition has yet to be determined.
Optimum working conditions of the system are extracted applying both passive and active control methods, to be used in the design of such systems.
To determine the effect of the chosen parameters on the system and optimum working conditions, an experimental design method suggested by Genichi Taguchi was used.
Response surface methodology (RSM) with Box Behnken design (BBD) was applied to investigate the effects of independent variables (iron particle, zeolite and current density) and their interaction on the system performance, also determining its optimum working state.
The opportunity to apply the same membrane in different configurations enables assessment and investigation ranging from the basic membrane properties, effects of membrane design and composition, to identification of optimum working conditions in different applications.
In this perspective, some analytical equations for the optimum working fluid temperatures, optimum thermal efficiency, optimal distributions of heat exchanger areas and optimum specific power output were found in terms of economical and technical parameters.
