热电比拟虚拟仿真教学实验的开发OA

Based on the principle of thermoelectric analogy,this study established an equivalent circuit for two-dimensional steady-state heat conduction objects incorporating isothermal,convective,adiabatic,and interface continuity boundary conditions and developed a virtual simulation teaching experiment to address the limitations in the thermoelectric analogy experimental teaching module,such as poor flexibility and difficulty in expansion due to constraints in circuit component quantity and scale.The experiment realized the simulation of isothermal and convective boundaries in the teaching experiment at our university,and was further augmented with the formulation of nodal heat balance equations,data export and other teaching support functions that help deepen students'understanding of the experimental principles.The heat balance deviation for two-dimensional corner conduction obtained from this simulation was compared with results from Ansys Fluent software,demonstrating reasonably high accuracy of the experiment.The newly developed virtual experiment has been implemented in two classes within the School of Energy and Power Engineering and is scheduled to be extended to experimental teaching in heat transfer courses university-wide.
