evaporation coefficient
1.In this paper, a real ant colony simulating algorithm (RACSA) which directly simulates the foraging behavior of ant colony, is proposed. The research on factors such as the importance of pheromone, evaporation coefficient of pheromone, amount of ant and the pheromone quantity deposited by ants is performed by simulated experiments and the results will be guidelines to theoretic research and design of other ant colony algorithms.
2.Comparing this cycle with the evaporation compression refrigerating cycle, the new cycle has more high coefficient of performance ( COP ) under the same condition.
3.The results show that this model can obtain a reasonable simula ting for the diurnal variations of heat balance, soil volumetric water content, re sistance of vegetation evaporation, flux of surface moisture, and profiles of tu rbulent exchange coefficient, turbulent momentum, potential temperature, and hum idity mixing ratio.
4.The effect of main operation parameters (evaporation temperature, condensation temperature, cycle ratio and the concentration of weak solutions) on the coefficient of performance (cop) was studied. The optimal parameters are obtained.
5.Mathematical simulation models were established to calculate and analyze refrigeration performance indices at varying temperatures of heat source,cooling water and evaporation,as well as differential concentration of solution. A comparison of coefficient of performance (COP) of the new double-effect NH3-H2O absorption cycle was made with those of for the traditional single-effect and doublestage cycles.
6.The main parameters calibrated in the model are dispersion coefficient(a=0.07, b=0.7), roughness length(0.02m), wind drag coefficient(Cwd=3%), and evaporation rate(0.1/d).
