This work presents a CFD model of a transversally-periodic bundle of four in-line tubes of a kraft recovery boiler bank for ash deposition calculations. The flue gas was laden with discrete solid ash particles. Particle contact and sticking–rebound mechanics were used. The ash deposition parameters (arrival rate, sticking efficiency, deposit rates) were computed locally, studying the dependency on...
The modeling of fuel chemistry within computational fluid dynamics (CFD) simulations of diesel and other compression ignition engines is important because fuel composition and properties can significantly influence engine performance. Modern detailed chemical mechanisms containing detailed descriptions of the elementary reaction pathways can provide predictive modeling of fuel chemistry; however,...
