Important parameters in the compartment models are the compartment size and the particle residence time.
Particle residence time equations for the cyclonic zone were derived by force analysis.
The particle residence time decreased in a power law as the SCR increased.
To extend the engineering application range of the particle residence time, a new Lagrangian-based approach, which adopts the kernel concentration estimation method, is herein proposed to model the particle residence time in indoor environment.
Particle residence times at the transfer surface ranged between 1 and 10 sec.
Variations of particle residence time with particle size, gas velocity, and wall position are examined.
Visual examination of particle distribution and statistical analysis of particle residence times of experimental data served as model validation.
Solid mass that flows out of the riser requires particle residence time to close the mass balance equation.
The performance is assessed by measuring the particle residence times, particle velocities, and the extent of segregation during discharge.
However, increasing the cone angle has a contrary effect because of the decrease in particle residence time.
The cTD allows longer particle residence time for the same flow rate, resulting in higher particle volatilization in some cases.
