  Numerical simulation of particle motion and heat transfer in a rotary kiln

  201611 · Through numerical simulation, the main factors that affect heat transfer in the kiln are found to be the gas temperature, diameter of the particles, and rotational speed of the rotary kiln. To discern the mechanism of heat transfer in the kiln, the influence of these three factors is investigated individually. 3.4.1.

  Improvement of a cement rotary kiln performance using artificial neural ...

  202095 · In order to investigate the effect of parameters and system optimization, the processes must be modeled first. Cement rotary kiln systems are complex because of non-linear, time invariant and full of behavioral uncertainty where the mathematical modeling of the plant is impossible. Artificial neural network (ANN) is one of the best tools for …
