Simulation Research on Microwave Heating Straw
Abstract: In this paper, we mainly study the temperature-rising characteristics about microwave heating straw, including theoretical research and numerical simulation. This process can be described by heat conduction equation; through simplifying the heat source term by Lambert law, we obtain the equation’s analytical and numerical solution with second boundary condition. We simulate the distribution of the temperature in the microwave heating process by means of Matlab. Through analyzing the graphic, we think that choosing the straw’s length at 0.5 meter is more appropriate, and heating the straw for 42 minutes can guarantee the heating efficient, and also will not lead to carbonization. The results obtained can be used for reference in engineering practice.
