in this study, a numerical model was developed to investigate the two-dimensional heat transfer in a homogenous finite cylinder to predict the local temperature and sterilizing value during caviar pasteurization. a fixed grid finite difference method was used in the solution of heat transfer equations according to crank-nicolson’s scheme. the model was validated by comparison of the experimenta...

Abstract This paper presents a method for optimizing the exploitation of mechanical eccentric presses based on mathematical model. model has been completed with graphic interface, through which whole series constructive and functional parameters can be modified, such as: radius crank, length connecting rod, mass pulley, transfer ratio between electric motor flywheel, moment inertia motor, frict...

This paper discusses a new methodology for the synthesis of planar four-bar linkages with rotary joints based on a desired coupler curve. This was performed by first deriving a closed-form expression relating the coupler points to the corresponding crank orientations, which in turn evaluated to zero when the desired point is reached exactly at the specified crank angle. The residual values of t...

Cyclists seek to maximize performance during competition, and gross efficiency is an important factor affecting performance. Gross efficiency is itself affected by pedal rate. Thus, it is important to understand factors that affect freely chosen pedal rate. Crank inertial load varies greatly during road cycling based on the selected gear ratio. Nevertheless, the possible influence of crank iner...

Continued fraction absorbing boundary conditions (CFABCs) are new arbitrarily high-order local absorbing boundary conditions that are highly effective in simulating wave propagation in unbounded domains. The current versions of CFABCs are developed for the non-dispersive acoustic wave equation with convex polygonal computational domains. In this paper, the CFABCs are modified through augmentati...
