This paper describes experimental studies of thermally driven acoustic oscillations of a gas column ("Taconis vibration ") generated in a pipe whose end is closed at the warm part and open at the cold part. The stability curves and the frequency diagrams of the oscillations are experimentally determ
## Abstract After an extensive literature survey the experimental thermalβconductivity data for twelve diatomic gases were utilized to produce an accurate and expedient means of predicting values over extensive ranges of temperature and pressure. Plotting values of __k__\* against __T__~__R__~ on l
