A thermo chromic materials named Salicylaldehyde ethanolamine Schiff base was synthesized with ethanolamine and salicylaldehayde derivative in the medium of ethanol, and was characterized by means of UV-Vis absorption, GCMS. The reaction kinetics of Schiff base production was investigated through UV-Vis absorption spectra, and also the thermochromism of Schiff Base Condensed from ethanolamine and...
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...
Mathematical model of melting problem of phase change material (PCM) in cool storage tank was established. Moreover, the effective heat capacity method was used to simulate the heat transfer processes of cool storage tank, the changing relation curves of melting ratio, temperature and the diameter of cool storage tank along with time were obtained. The results show that the time of the ambulatory...
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...
