LG type vacuum freeze dryer vapor captor is taken as the study object, and a mathematical model of frost heat transfer of the vapor captor was established, the effective heat capacity method was used to simulate the heat transfer processes of vapor captor. Frosting mechanism under low temperature and low pressure condition was investigated, and the changing relation curves of temperature distribution,...
Based on the mathematical model of wet clutch engagement, a dynamic model of a tracked vehicle was developed by means of the software Matlab/Simulink. This model can be used to simulate the shift schedule, piston pressure and relative velocity. A two dimensional heat conduction model was also developed with reasonable selection of proper boundary conditions, contact pressure model and heat flux distribution...
Food requires strict temperature control throughout the so-called 'cold-China', in which a particular storage temperature is need for each link. Display cabinets are known to be the weakest link from this point of view and, therefore, particular attention is paid to their design. And it is a real challenge for manufacturers and users of refrigerated display cabinets to provide the products with minimal...
