Abstract: Local and average blade temperatures were calculated for two stationary air-cooled turbine blades with 10 tubes and 13 fins forming the internal heat-transfer surfaces. These temperatures were calculated using previously published NACA temperature-distribution equations and the most recent theories for determining heat-transfer coefficients, including for the first time the allowance for effects of variable wall temperature on gas-to-blade heat-transfer coefficients at the leading and trailing sections of turbine blades. Comparison of calculated and experimental blade temperatures, for gas temperatures of 300° and 1000°F, resulted in good agreement.
Originally developed in 1993 for an auction of an Architect's private collection of over 1,500 drawing instruments and calculators; this extensive book is one of a few comprehensive references available for comparative study of these instruments. The original collection was assembled over a twelve year period from sources in the US and Europe. Each instrument is listed in a scientific format for comparative evaluation and identification. An abbreviations table supports this approach. Profusely illustrated with 113 color photos and 61 highly organized text pages. The Subject Index has over 400 individual references dissecting this impressive collective of instruments from the 18th C. thru the...
