Reviewing particle size deposition results

Range of particle diameters

Two sizes chosen

Worst case scenario : 10μm

When measurable deposition begins : 4μm

12-10-13 Team 14054 22

Results Summary

ISO Standards : 2 s in between puffs

Tubing Design : 18 in of horizontal tubing

Settling Time Settling Length

10 μm 1.9 s 14.9 in

4 μm11.99 s 94.09 in

12-10-13 Team 14054 23

Conclusion

10 μm particles would have a chance to settle 4 μm particles would not have a chance to settle Negligible deposition of particles larger than 3.2 μm Most deposition occurs in particles ranging from 1μm to

0.18 μm

Negligible particle loss due to sedimentation

1. Clean air enters testing atmosphere via negative pressure from ventilation.

2. Clean air is drawn to fishtail chimney via negative pressure from sidestream flow (3 SLPM)

a. Air is drawn into tip of cigarette via mainstream negative pressure.

i. Oxygen in air is burned for fuel in cigarette.

ii. Air picks up various vapors are smoke particles. (Higher temperature).

iii. Air passes through cigarette butt. (Filters out some larger particles).

iv. Air passes through cigarette holder.

v. Air passes through one of the mainstream collection systems.

1. Collection filter collecting most of the particles. (Pressure drop and restricted flow).

2. Lung cast particle deposition setup consisting of:

a. Through humidification chamber adding moisture.

b. Through lung cast.

c. Exits through multiple exit points on lung cast into tubes.

d. Consolidates with the other flow paths in the collection chamber.

vi. Air passes through equipment protection filters. (Pressure drop and restricted flow).

vii. Air is drawn into syringe pump.

viii. Air is expelled from the syringe pump to exhaust flow path.

12-10-13 Team 14054 40

b. Air is continues up fishtail chimney via negative pressure from sidestream flow (3 SLPM)

i. Air mixes with sidestream smoke.

ii. Air converges into a tube.

iii. Air is filtered through main sidestream filter. (Pressure drop and restricted flow).

iv. Air passes through impinger to collect leftover particles. (Pressure drop, restricted flow, bubbling flow).

v. Air passes through secondary filters to “clean” air and protect equipment. (Pressure drop and restricted

flow).

vi. Air is drawn into sidestream pump

c. Air is expelled to ventilation.

Ideal gas law: P*V = n*R*T

Or: P = ρ*T*R/M

So: ρ = P*M/(R*T)

P = Absolute Pressure V = Volume R = Gas Constant T = Temperature ρ = Density M = Molar Mass
