Thermal protection system (TPS) typically use materials which ablate at high temperature for mass-efficient rejection of aerothermal heat load. A reliable numerical procedure that can compute surface recession rate, mass loss, surface heat flux, and surface temperature distribution under general heating conditions is essential to successfully carry out the design of an optimum TPS. Thus, in order to improve estimating of the heat flux over an ablating surface, a flow solver coupled with ablating surface conditions becomes a requirement. A study have been conducted to predict nozzle recession behaviour in a solid rocket motor nozzle and for broad variations of motor operating conditions.

Abstract
Thermal protection system (TPS) typically use materials which ablate at high temperature for mass-efficient rejection of aerothermal heat load. A reliable numerical procedure that can compute surface recession rate, mass loss, surface heat flux, and surface temperature distribution under general heating conditions is essential to successfully carry out the design of an optimum TPS. Thus, in order to improve estimating of the heat flux over an ablating surface, a flow solver coupled with ablating surface conditions becomes a requirement. A study have been conducted to predict nozzle recession behaviour in a solid rocket motor nozzle and for broad variations of motor operating conditions.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
