摘　　要：“空气外掠单管对流换热”是《工程传热学》基础教学实验之一,但限于实验设备的体积和造价,教学实验室通常无法配置足够的台套数;且该实验等待周期长,噪音大,导致学生积极性低,授课质量不佳。为了解决这些问题,实验中心开发了对应的虚拟仿真教学系统。该系统高度还原现场实验场景和操作步骤,采用底层数学模型计算参数变化,实时更新参数曲线,可让学生了解传热过程的变化情况;并设置理论教学、考试答题、实验报告、成绩统计等模块,功能全面,使用方便。经上线实测,该系统极大缩短了实验周期,丰富了实验教学内容,增强了趣味性,有效提高学生参与度和授课质量。“Air swept single tube convection heat transfer”is one of the basic teaching experiments of“Engineering Heat Transfer”.However,due to the volume and cost of experimental equipment,the teaching laboratory usually cannot be equipped with enough sets.In addition,the experiment has a long waiting period and loud noise,resulting in low enthusiasm of students and poor teaching quality.In order to solve these problems,the experimental center developed the corresponding virtual simulation teaching system.The system highly restores the real experimental scene and operation steps,uses the underlying mathematical model to calculate parameter changes,and updates parameter curves in real time,so that students can understand the change of heat transfer process.And set up the theory teaching,examination answer,experimental report,score statistics and other modules,comprehensive function,easy to use.According to the online measurement,the system greatly shortens the experimental cycle,enriches the experimental teaching content,enhances the interest,and effectively improves the student participation and teaching quality.
