Thermal conductivity of a WTiNSiC hot shell emitter for a thermionic energy converter

The thermal conductivity of a WTiNSiC hot shell for a thermionic converter was measured by the flash diffusivity technique. From the data obtained, it is shown that at the operating temperature of 1400 °C the temperature difference across the hot wall is of the order of only 7 °C, which ensures ma...

Summary:The thermal conductivity of a WTiNSiC hot shell for a thermionic converter was measured by the flash diffusivity technique. From the data obtained, it is shown that at the operating temperature of 1400 °C the temperature difference across the hot wall is of the order of only 7 °C, which ensures maximum operating efficiency without requiring excessive combustion temperature.
