Abstract

The present application discloses a regenerator design method for a ceramic hollow brick regenerator. The method includes: discretely processing a preset regenerator in space and time to obtain multiple units and multiple time steps. Calculate the air flow temperature and heat accumulator temperature in each unit and each time step; calculate the corresponding air flow temperature and heat accumulator temperature for each time step and each unit according to the air flow temperature and heat accumulator temperature The actual stress average temperature difference is determined by judging whether the actual stress average temperature difference corresponding to any time step and any unit is greater than the preset maximum stress average temperature difference; The body temperature distribution curve is recalculated to obtain a new airflow temperature and a new heat storage body temperature until the actual stress average temperature difference is less than the maximum stress average temperature difference. The present application solves the technical problem that the thermal storage body in the prior art cannot meet the actual needs.

Description

technical field [0001] The present application relates to the technical field of regenerators, and in particular, to a method for designing a regenerator of a ceramic hollow brick regenerator. Background technique [0002] In the field of hypersonic wind tunnels, pure air heating technology has always been a difficult and hot issue. The main heaters include metal thermal storage heaters, metal continuous heaters, graphite electric induction hollow brick thermal storage heaters, and ceramic ball thermal storage heaters. Heaters, ceramic hollow brick regenerative heaters and other forms. Among them, in the case of long-term operation of the ceramic hollow brick regenerative heater, it generally includes the alumina ceramic hollow brick regenerative heater type that provides 2000K pure air and the zirconia ceramic hollow brick regenerative heater type that provides 2600K pure air. Therefore, the ceramic hollow brick regenerative heater is an important part of pure heating tech...
