Abstract
The present disclosure discloses a performance evaluation method of a LNG ambient air vaporizer, comprising: step 1, performing a site test on an actually-operating LNG AAV and obtaining its parameters, performing a fluid-thermal coupling calculation and simulation of the LNG AAV by use of FEA software, then performing model modification based on the test results; step 2, performing fluid-thermal-structure coupling calculation of an AAV for validation in the FEA software, adding a submodel module for optimization and validation tests; step 3, performing fluid-thermal-structure coupling calculation on the LNG AAV to be evaluated under a design operation condition and an operation condition of the AAV to be put into service in a certain region, and evaluating the LNG AAV according to the results. The present disclosure can evaluate vaporization performance and fatigue life of the AAV simultaneously and has good operability and economical efficiency.
