Abstract
The film theory solution is presented for heat transfer accompanied by a chemical reaction having a finite reaction rate. Results are obtained for the N02 decomposition reaction, but the use of dimensionless groups in the analysis allows general conclusions to be made for other chemical systems. The dimensionless temperature driving force is varied from 0 to 2, corresponding to a driving force of 0 to 190 deg F for the NO2 system. A modification of the linearized theory results in an approximating equation which agrees with all of the results to within 3.7%. Experimental data are presented for the rate of heat transfer to decanposing nitrogen dioxide in the turbulent boundary layer on the surface of a rotating cylinder. Experiments were performed for gas temperatures between 830 deg F and 1012 deg F and for pressures in the range of 2 to 11 atmospheres. The speed of the rotating cylinder was varied from 320 to 1090 rpm. Uder these conditions, heat transfer rates to the reacting system are limited by the kinetics of the decomposition and recanbination reactions.
