✦ Synopsis

A~traet-A simple one-dimensional mathematical model is developed which is used to calculate the burning rate of a spray of droplets with an initial Rosin-Rammler size distribution. The model is based on experimental observations of the influence of temperature, partial pressure of oxygen, and droplet size on the burning rate of a single droplet. In addition, balance equations are employed to determine the time dependent parameters of the rate equation. The model is used to show the significance of various input parameters on the combustion rate (i.e. evaporation rate) of the spray. The validity of the model is examined by comparing predicted changes in combustion efficiency with those obtained previously from a single tubular turbojet combustor operating with liquid iso-octane over a range of inlet oxygen concentrations.

A consideration is provided of the possibility of identifying changes in the residual unbalance of a multi-bearing rotor system. It is assumed that the relative motion of the rotor journals with respect to the bearings can be measured before and after the change in unbalance take place. Furthermore,
