Superposition calculation of frozen temperature field and its computer method |
| |
| Abstract: | With the steady heat transfer model of circular pipe, it is convenient to calculate and analyse the temperature of any position with the unity of temperature calculation in the frozen and temperature dropping region. According to the conductivity law due to temperature difference, superposition calculation formula of frozen temperature field is is established under the condition of double or more rows of freezing pipes. Calculation and analysis of the temperature of each node in the discrete region with the deflection of freezing pipes can be realized conveniently with the computer method. The analytical method is proved to be convenient and practicable with both the simulation calculation and the analysis on the engineering practice. This method provides a foundation for the information controlling and monitoring system of the analysis of temperature field with freezing construction. |
