Mathematical Modeling in Coal Technology

The talk will be suitable for a general audience.

Students are strongly encouraged to participate.

Abstract



The talk will consist of four parts, the first two review the problem areas of interest and the discrete model for agglomeration developed last year, the last two solve the model:

1. Brief Review of Some Problem Areas in Mathematical Modeling in Coal Technology. Agglomeration and coagulation of particles in coal combustors and gasifiers creates slagging and fouling. Currently mechanistic models are being developed for various aspects of various processes. However, the completion of a realistic model for use with computer models of combustors and gasifiers remains a future goal. Emphasis will be placed on modeling of agglomeration of fly ash in an entrained flow reactor and on the coalescence of bubbles in the wake of a ship.
Prerequisite: None

2. Very Brief Review of the Derivation of a Discrete Model for Agglomeration. Starting with the basics, the standard discrete model for the agglomeration of particles can be developed from first principles.
Prerequisite: Knowledge of the concept of a derivative.

3. Derivation of the Solution of the Discrete Model. Standard techniques for solving differential equations (Math 18) will be used to obtain the general solution of the model for any initial conditions.
Prerequisite: Math 18 is helpful but knowledge of the concept of a derivative is probably sufficient.

4. Consideration of Initial Conditions. Various initial conditions will be applied to the general solution.
Prerequisite: Math 18 is helpful but knowledge of the concept of a derivative is probably sufficient.
