- Abstract
- The ability to determine the important and controlling chemical and physical processes of practical engineering systems is important to (scale) model development and evaluation. In the present paper, sensitivity analysis procedures, in which the responses of variables or parameters to variations in others, are used to make such determinations. Depending upon the nature of the phenomena or problem, which may require both theoretical and experimental input. Examples are given for the combustion of pool fires and the chemical kinetics of thermal reacitons and reactors. conductivity of the oil is needed, but to the best of our knowledge, such data are not generally available. Thermal conductivity values for some pure, low-molecular-weight liquid hydrocarbons can be found, but crude oil is a mixture of a large number of rather heavy hydrocarbons. It is difficult then to determine thermal conductivity values for curde oil using data for pure compounds and the correlations available for determining the thermal conductivity of liquid mixtures.
