摘　　要：煤炭资源开采向深部煤层的进军使瓦斯治理问题日益凸显,对高质量复合型人才的培养提出了更高要求。瓦斯掺混燃烧实验涉及易燃易爆气体,伴随高温和有害气体排放,具有较高的危险性。为解决传统瓦斯燃烧利用实践教学安全风险高,教学手段单一的问题,面向工程背景与教学现状重构了实验教学的知识架构与教学目标,吸纳前沿科研成果与工程技术应用案例,基于Unity 3D开发了仿真实验软件,形成超低浓度瓦斯燃烧与烟气排放成分检测虚拟仿真实验系统。该系统为受训人员提供了高度还原现实的可视化交互式教学模式,提升了学习的灵活性和安全性,有利于工程实践能力的培养。[Objective]The advancement of coal resource exploitation in deep coal seams has increasingly highlighted the issue of gas control,posing higher requirements for the cultivation of high-quality,composite,and outstanding talents.Practical teaching is an important process for achieving teaching and training goals because it can cultivate high-quality,innovative talents.However,owing to the flammable and explosive gases involved,traditional practical teaching of gas combustion and utilization is restricted by high safety risks and simple teaching methods,which makes it difficult to cultivate students’practical engineering abilities.To address these problems,a virtual simulation experimental system for ultra-low-concentration gas combustion and smoke emission component detection is constructed based on Unity 3D.[Methods]A simulation system is constructed according to the experimental scenarios of gas combustion and utilization based on a gas turbine and an infrared flue gas analyzer produced by Capstone.First,the knowledge architecture and teaching objectives of experimental teaching are reconstructed according to cutting-edge scientific research achievements and engineering technology application cases of low-concentration gas combustion and utilization.Subsequently,a five-layer architecture for the virtual simulation software system is designed according to the teaching requirements of virtual simulation experiments for gas turbines.As the experiment of gas combustion and smoke emission includes both physical models and unstable processes,it requires different strategies for modeling.For physical devices in the solid state,the experimental setup is divided into eight modules,and each device of the submodules is built in Blender.For transient,unstable processes,such as flame propagation,a virtual reality method for the three-dimensional dynamic display of transient structures driven by reconstruction data of the temperature field is proposed.Finally,according to the functional attributes of the physical apparatus,s
