... an attractive technology for coupling with a downstream turbine. Numerous configurations of RDCs have been studied using simulations/experiments [ 9 , 10 ]. Several numerical investigations have been conducted to understand the complex and highly dynamic nature of the flow field [ 11 – 13 ]. Experimental...

... of the coefficients published in Ref. [ 2 ]. In Table 2 , the values of D32 in planes 0 and 2 are given for all the considered turbines and these calculated values are compared with the experimental results. The use of K Gnew for the condensation model represents an acceptable agreement between experiments...

... to determine the droplet size distribution and associated representative average diameters generated. A series of test conditions were run between 50 m/s and 175 m/s using multilevel factorial designed experiments. The results obtained were subjected to analysis of variance to generate correlations for breakup...

... based on experiment and numerical means. The results show that first, distortion of energy and exergy is relatively significant during shorter transient time. Fuel incomplete combustion is the root of energy and exergy distortion during transient process. Second, low intake air temperature is helpful...

..., and minimum film thicknesses. Experimental verification is conducted at 10, 15, and 20 krpm. The measured load capacity and frictional loss agree well with the prediction. The measured film thickness also agrees with the prediction after the structural deflection of the thrust runner disk is compensated...

...Shun-sen Wang; Guan-wei Liu; Jing-ru Mao; Qun-gong He; Zhen-ping Feng This paper experimentally examines the influence of coating thickness, test temperature, coating hardness, and defects on the erosion resistance of boride coatings, ion plating CrN coatings, and thermal spraying coatings...

... bearing test-bed is designed and established, and the speed is more than 30,000 rpm. Experiments including the influence of different radial clearance on rotor dynamical characteristics, speed run-up and coastdown, etc., have been done on the test-bed. The experimental results show that radial clearance...
