[0120] Example
[0121] In order to verify the correctness of the determined contact thermal conductivity model, a set of confirmatory tests were carried out. The test results are shown in Table 9.
[0122] Table 9 confirmatory test data
[0123]
[0124]
[0125] (1) Use the determined empirical formula of contact thermal conductivity: h s =0.1566T 0.371 P 2.061
[0126] When temperature and pressure are applied at the same time, the data in Table 10 is calculated:
[0127] Table 10 Contact thermal conductivity data
[0128]
[0129] (2) Use the determined empirical formula of contact thermal conductivity: h s =0.5013P 2.18
[0130] When only considering the influence of pressure, the data in Table 11 is calculated:
[0131] Table 11 Contact thermal conductivity data
[0132]
[0133] Through the above examples, it can be concluded that the test method provided by the present invention can directly enter the temperature and pressure data into the formula when the temperature and pressure ...
