To study the influence law of overburden rotating plate mechanism on fragmentation and separation potato soil agglomerates, a single-factor test response surface simulation analysis process were conducted in EDEM 2022 software. The results show that triangular rack blade overburdened has best effect separation. With increase lower speed, upper lift chain bar line tilt angle mechanism, agglomera...

plate heat exchangers are widely used in industries due to their special characteristics, such as high thermal efficiency, small size, light weight, easy installation, maintenance, and cleaning. the purpose of this study is to consider the effect of depth, angle, and pitch of hemispheric chevrons on the convective heat transfer coefficient and pressure drop. in the simulation of the heat exchan...

The thermal effect of cool jets issuing into an incompressible hot cross flow at an angle over a turbine blade is the subject. Numerical solutions for twelve multiple flow arrangements with two flow ratios, two different hole spacing and four different jet issuing angles document strong to moderate secondary vortex structures spanning normal to the direction of the jet. This fully three-dimensi...

PURPOSE We have experienced a major fall in the economy in the recent past. We need something to help boost the economy. Our non-renewable sources of energy are also running out. We desperately are in need of an alternate renewable clean resource for energy. In doing this project, the researcher hopes to find the most efficient combination of blade angle and width on a wind turbine. HYPOTHESIS ...

The blades of wind turbines are the most important parts in producing power output. In this study, a section of a 660 KW wind turbine blade will be installed in Iran in near future was tested in a wind tunnel. In addition to steady tests, various unsteady tests including the effects of reduced frequency, mean angle of attack, and amplitudes were carried out. The preliminary results show strong ...

in the present paper, the aeroelastic stability of helicopter rotor blade is determined using aeroelastic frequency response function. the aeroelastic model of blade is obtained by combining dowell - hodges beam model with loewy unsteady aerodynamic theory which considers an unsteady wake beneath the rotor. equations are formed and aeroelastic frequency response functions are obtained by invert...

a r t i c l e i n f o Keywords: Mixing performance DEM MGMMI Blade-rake angle Bladed mixers This study focuses on the understanding of flow over a single blade and its impact on powder mixing. The Discrete or Distinct Element Method (DEM) is used and the flow of a single blade through a bed of a binary particle mixture is studied. Mixing performance with respect to a blade-rake angle and partic...
