Apparatus for determining the temperature distribution of a polymerization reactor, and program for determining the temperature distribution of a polymerization reactor

摘要

A device for determining the temperature distribution of a polymerization reactor, for determining the temperature distribution in a gas phase polymerisation reactor containing, comprising:the calculation means for the velocity field of a particle for calculating the positions and the speeds of all the particles in a stirring field to predetermined individual times at intervals over a discrete - element - the method,an averaging means for calculating the average value of the part of the same speeds, to each of the times in each of the elements, which, by means of a division of the gas phases polymerization reactor, in predetermined units are obtained, and further for calculating the time-averaged satellite particle velocity in each of the elements thereof,a correction means for the particle velocity for correcting the time-averaged satellite particle velocity in each of the elements, in order to maintain a masses to satisfy equation for particles,the calculation means for the gas - liquid - speed for the use of the corrected particle velocity than the initial value of the gas - liquid - speed,a correction means for the gas - liquid - speed for correcting of the initial value of the gas - liquid - speed in each of the elements, in order to maintain a masses equation for gas - liquid to meet,the calculation means..
