... Abstract Many piezo-electrical crystals such as quartz are grown hydrothermally in highly pressurized cylindrical autoclaves. In hydrothermal crystal growth of quartz, quartz pellets are put in the bottom of an autoclave where the temperature is higher and the quartz dissolves into an aqueous...

... Autoclave process is a widely-used method of composite materials manufacturing. The uniformity of temperature fields during the composite curing process has an important effect on the component and then product quality. Previous simulations on composite curing temperature field had some...
