| 摘 要： | 应用激光全息干涉仪并配合红外扫描热象仪，测量了空气绕流球形发热体的温度场，以研究模拟固体颗粒燃烧发热条件下的传热特性及其影响因素。通过试验，获得了球体局部换热数Ｎｕ沿球极θ角的分布，球体平均换热数，及Ｎｕ和受和Ｔ＿ｓ／Ｔ＿０影响的经验关系式。

| Abstract: | The temperature field around a heasing solid sphere is measured with both laserholography and infrared scanning technique to study the hest transfer tharacteristics of solidpartieles in combustion. The local Nusselt number Nu along the sphe re polar angle , theaveraged Nusselt nu-mber Nu, as well as their empiral correlatisn affected by Re and Ts/TOaer obtained. |
