Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
129 words
A METHOD OF DETERMINING THE ENERGY OF A HIGHTEMPERATURE LAMINAR FLOW GAS STREAM AT A PREDETERMINED POINT THEREIN COMPRISING POSITIONING A HEAT CONDUCTIVE BODY HAVING A CURVED SURFACE WITH A KNOWN VELOCITY GRADIENT AT THE PREDETERMINED POINT TO ENABLE HEAT FLOW THROUGH THE BODY TO BE DETERMINED BY SENSING THE TEMPERATURESAT LONGITUDINALLY SPACED POINTS, ALIGNING THE CURVED SURFACE IN THE STREAM PARALLEL TO THE LAMINAR FLOW THEREBY ENABLING THE HEAT FLOW TO BE EQUATED TO THE HEAT INPUT AT THE CURVED SURFACE TO DETERMINE ENTHALPY, SIMULTANEOUSLY COOLING THE BODY, SENSING THE TEMPERATURE AT SAID LONGITUDINAL SPACED POINTS, AND CALCULATING THE HEAT FLOW THEREBY ENABLING THE ENTHALPY OF THE GAS STREAM TO BE DETERMINED BY EQUATING SAID HEAD FLOW WITH THE HEAT INPUT TO SAID BODY AT SAID CURVED SURFACE.
