一维非稳态导热问题的红外热诊断方案
Infrared Thermal-diagnosis of One-dimensional Unsteady Heat Conduction Problem
【摘要】 结合红外热诊断由表及里的诊断功能,以无限大平板为研究对象,建立了一维非稳态导热的反问题模型,并给出了该反问题同步分析的向后差分方法,确定了这类非稳态导热反问题的红外热诊断方案。
【Abstract】 According to the infrared thermodiagnosis,this paper takes an infinity flat as studying object.An unsteady inverse model is constructed to identify the unknown boundary temperature division by using backwards finite difference method.It can be drawn from this study that one-dimensional unsteady inverse heat conduction problem can be thermal-diagnosed.
