Current grain filling temperatures are already approaching critical levels in many rice growing counties, resulting in high occurrence of grain chalkiness, currently a major problem for rice production in Asian countries [ 4].
CAE simulation softwares, in particular, MoldFlow, are used to get wax injection moulding parameters such as filling parameters, temperature profiles, freeze time, speed, and pressure.
In this injection molding process, the machining parameters, namely the mold temperature, melt temperature, filling pressure and filling time are optimized with considerations of multiple performance characteristics including the strength of welding line, the shrinkage and the difference of forming distributive temperature.
It is generally accepted that rice grain traits are affected by temperature during grain filling, with high temperatures decreasing head rice ratio and increasing chalky rice ratio (Kobayashi et al. 2008; Kwon et al. 2011; Nishimura et al. 1985).
All the air holes are assumed to be filled with temperature sensitive liquid.
Casting defects deviated from the center line of the part, and the degree of deviation is affected by the mould filling process and temperature fields.
These results are suggesting that weak interactions between the adsorbed hydrogen molecules and MOF crystals is occur in mesoporous regions and the adsorption into macroprous which are filling in high temperature shows strong interaction.
Cool the filling to room temperature.
An experimental setup is designed to enable the curing of CPB samples under different stresses, filling rates, initial temperatures and drainage conditions as well as the monitoring of the changes in capillary pressure, temperature, amount of drained water and electrical conductivity in the CPB samples during curing.
The transient behavior of the pulse tube engine's underlying thermodynamic properties is studied numerically and experimentally under different design parameters as well as for different heat input temperatures, filling pressures and operating frequencies.
