Multi Physical Field Analysis of Microwave Freeze-drying Process for Geothermal Porous Materials
Using mannitol and lactose as raw materials,ice cream was prepared using liquid ni-trogen to prepare geothermal porous materials with different initial saturations.By using a multifunc-tional microwave freeze-drying device,the geothermal porous material prepared is freeze-dried,es-tablish a multi physical field analysis model for the drying process of geothermal porous materials,and design corresponding solution conditions.By using COMSOL multi physical field simulation software and combining with definite solution conditions,a multi physical field analysis model is solved to com-plete physical field analysis under different initial saturation and microwave power conditions.
