This paper reports work on the two and three-dimensional numerical simulation of dough mixing with free surfaces, that arises in the food processing industry. Free surface flow in a rotating cylinder is investigated when a fluid is mixed in a cylinder with a stirrer. Different dough mixer designs are investigated. The rotating stirrer may be placed either in a concentric or eccentric arrangemen...
Magnetohydrodynamic simulations of fully convective, rotating spheres with volume heating near the center and cooling at the surface are presented. The dynamo-generated magnetic field saturates at equipartition field strength near the surface. In the interior, the field is dominated by small-scale structures, but outside the sphere by the global scale. Azimuthal averages of the field reveal a l...
introduction: strength training has an important role in the exercise programs of normal individuals and athletes and it also has numerous benefits on the health of human body and spirit. one of the types of these exercise is eccentric resistance exercise which is associated with negative physiological changes. thus: this study examined the effects of a single bout of eccentric resistance exerc...
We present a new endoscopic system that provides two different views simultaneously, one is a wide view (120 degrees) and the other is a zoomed view with image-shift mechanism. A Porro prism (II) is used to shift the zoomed image vertically and horizontally. With this endoscope, surgeons can observe throughout the surgical field without moving or rotating the endoscope itself. We have evaluated...
Pattern formation of a thin layer of vertically agitated wet granular matter is investigated experimentally. Rotating spirals with three arms, which correspond to the kinks between regions with different colliding phases, are the dominating pattern. This preferred number of arms corresponds to period tripling of the agitated granular layer, unlike predominantly subharmonic Faraday crispations i...
A bidisperse medium of large sand particles and small glass beads is mixed in a cylindrical vessel that put rotational motion around an eccentric static rod. The subsequent segregation occurring the system investigated primarily at free-surface where concentration globally increases towards limit value while oscillating. In order to gain deeper understanding intrinsic mechanisms causing segrega...
The maximum volume of liquid bridge left between two vertically mounted spherical particles has been theoretically determined and experimentally measured. As the gravitational effect has not been neglected in the theoretical model, the liquid interface profile is nonsymmetrical around the X-axis. Symmetry in the interface profile only occurs when either the particle size ratio or the gravitatio...
