A simplified population balance model has been developed to predict the Sauter mean diameter, and optimize any breakage coalescence kernel. Firstly, shortcut is detailed, simplifying assumptions are argued. Then applied in a comparison of 60 combinations selection classical breakage, collision frequency efficiency kernels. The models fitted then compared with an experimental dataset measured tw...

This study conducted cold flow experimental research on the influence of mass rate atomization characteristics screw conveyer swirl injectors in an opening environment. The Phase Doppler Particle Analyzer (PDPA) and high-speed photography were utilized to obtain data. results showed that greatly influenced establishment working injectors. design point selection exerted significant range perform...

An electromagnetic levitation technique superimposed with a static magnetic field was used to investigate the effects of convection and cooling rate levitated molten Cu80Fe20 alloy on size morphology induced phase separation structures formed during undercooling. The obtained results were compared our previous works Cu80Co20 alloy, in terms phase-separated dispersed Fe-rich phases. It revealed ...

The potential of Palm Methyl Esters (PME) as an alternative fuel for gas turbines is investigated using a swirl burner. The main air flow is preheated to 623 K and a swirling spray flame is established at atmospheric pressure. The spray combustion characteristics of PME are compared to diesel and Jet-A1 fuel under the same burner power output of 6 kW. Investigation of the fuel atomizing charact...

The data presented here supports the informational background of enzyme-based lignocellulose hydrolyzation, cellulase characterization, and sugar yield prediction for the work "Enzyme-based lignocellulose hydrolyzation - Sauter mean diameter of raw materials as a basis for cellulase performance characterization and yield prediction" by Glaser [1]. Glucose yields from the enzymatic hydrolysis of...

In this paper, we present an experimental study on mass transfer of oxygen into water in an oscillatory baffled column (OBC). The objective of this work is to establish the contribution of individual parameters, such as the size of bubbles and the gas holdup, to the overall volumetric mass transfer coefficient (kLa). Our results show that the gas holdup is the most important factor. The liquid-...

estimating fetal weight in utero, for better management of pregnancy and appropriate timing of delivery especially in high-risk pregnancies is necessary. our purpose to evaluate a simple method in estimating fetal weight in iranian pregnant patients and also to compare was with a previous western study. this study was carried out in arash hospital, tehran university of medical sciences in 1996-...

A critical review on the improvement of penetration theory is presented in this work. The volumetric liquid-phase mass transfer coefficients kLa seven different liquids (1-butanol, 2-propanol, anilin, decalin, nitrobenzene, tetralin, and ethylene glycol) aerated with air a small bubble column (BC) (inner diameter: 0.095 m) were measured at ambient conditions further analyzed. It was found that ...
