Multi-objective optimization of venturi scrubbers using a three-dimensional model for collection efficiency
Multi-objective optimization of a venturi scrubber was carried out using a three-dimensional model for collection efficiency and non-dominated sorting genetic algorithm (NSGA). Two objective functions, namely (a) maximization of the overall collection efficiency, and (b) minimization of the pressure drop were used in this study. Three decision variables including two operating parameters, viz l...
متن کاملParticle collection efficiency in a venturi scrubber: comparison of experiments with theory.
Particle collection efficiencies in 23 size intervals covering a diameter range of 0.32-2.8 pm were measured for venturi scrubbers with throat diameters of 3.2,5.4, and 7.6 cm. Each scrubber was operated with four types of liquid injection, throat gas velocities from 21 to 160 m/s, and liquid-to-gas volume ratios from 0.000 19 to 0.0043. Results were compared to three widely used theoretical mo...
متن کاملIntroducing a New Formula Based on an Artificial Neural Network for Prediction of Droplet Size in Venturi Scrubbers
Droplet size is a fundamental parameter for Venturi scrubber performance. For many years, the correlations proposed by Nukiyama and Tanasawa (1938) and Boll et al. (1974) were used for calculating mean droplet size in Venturi scrubbers with limited operating parameters. This study proposes an alternative approach on the basis of artificial neural networks (ANNs) to determine the mean droplet si...
متن کاملDetermination of the Pressure Drop Across an Arterial Stenosis Utilizing Angiocinedensitometry *
A method is presented for an evaluation of the hemodynamic significance of a stenotic lesion in the arterial tree.Twenty-three patients were examined with arteriosclerosis obliterans and intermittent claudication of the same severity. Flow velocity data obtained by angiodensitometry and viscosity values calculated from the hematocrit were inserted into the Poiseuille's flow formula to obtain th...
متن کاملPressure drop across artificially induced stenoses in the femoral arteries of dogs.
Stenoses were artificially induced in 13 large mongrel dogs by implanting small hollow cylindrical plugs in their femoral arteries. The instantaneous pressure drop across the stenosis and the flow rate were measured for a series of stenoses varying in severity from 52.3 to 92.2%. Mean pressure drops ranged from approximately 2 to 30 mm Hg with peak pressure drops ranging from 9 to 53 mm Hg. The...
