Wall Temperature Spectrum Determination for High Temperature Heat Exchangers (HTHE) with Extended Surfaces

Development of C - SiC ceramic compact plate heat exchangers for high temperature heat transfer applications

This paper investigates the use of polymer and liquid silicon infiltrated carbon/siliconcarbide composite (C-SiC) materials for the development of inexpensive compact heat exchangers, as part of efforts for thermochemical hydrogen production. These heat exchangers will be capable of operating in the temperature range of 500 to 1400°C with highpressure helium, liquid fluoride salts (a potential ...

High Accuracy Multi-color Pyrometry for High Temperature Surfaces

An evaluation of previously proposed least-squares multi-color pyrometry methods was carried out to determine their highest achievable accuracy. The study was limited to the visible spectrum and the temperature range of 1700 to 3000 K, typical of electrode surfaces in high-power electric propulsion thrusters. A Monte-Carlo simulation of the various methods showed the effects that the number of ...
