摘要:
建立了一种1L慢烤燃装置模型，通过数值模拟分析其内部温场分布的影响因素和机理,通过改变模型中隔板尺寸、导流板形状、风扇数量和风扇转速等条件，研究了各种工况下烤燃装置内烧瓶周围温场分布。模拟结果表明，风扇数量与转速、隔板尺寸、导流板形状均会影响烧瓶周围温场分布的位置，但仅有风扇转速会影响温场响应的灵敏度、温场达到稳定所需时间和温场分布均匀性。理想的慢烤燃装置可实现的温场分布性能为：响应时间低于1 s，达到稳定时间低于30 s，均匀度在0.2 ℃左右。建立试验装置，在烧瓶外侧布置温度传感器，所得温场分布和温场均匀度与模拟结果一致。
Abstract:
A 1L slow cookoff device model was established. The influence factors and mechanisms of temperature field distribution in the slow cookoff device were simulated. Temperature field distribution around the flask was studied under diverse operating conditions by changing partition size, guide plate shape, number of fans and rotation speed of fans used in the model. The simulation results show that the number and rotation speed of the fans, partition size and guide plate shape will affect the position of temperature field distribution around the flask, but only the fan rotation speed affects the sensitivity of temperature field response, the time required to reach a steady temperature field and temperature uniformity. An ideal slow cookoff device can realize some performances as follows: response time is less than 1 s, the time to reach stable temperature is no more than 30 s and temperature field uniformity is about 0.2 ℃。When the testing device is established and temperature sensors are equipped outside the flask, temperature filed distribution and temperature uniformity tested are consistent with the simulation results.
