Estimating effective isothermal aging temperature

Technical Report ·
OSTI ID:5529686
Equivalent temperatures for isothermal aging to simulate fluctuating ambient temperatures are calculated where T(t) is temperature-time function for sinusoidally varying annual and diurnal cycles and ..delta..E is an activation energy and the average is evaluated from mid-winter to mid-summer. The difference between the effective temperature, T/sub i/, and the mean temperature, for conditions approximating those of arid temperate climates, was found to be as high as 16/sup 0/ celsius. For diffusion controlled reactions the temperature difference can be 7 to 10/sup 0/ celsius.
