Ventilation System Design for Odor Management
Updated: Jul 31, 2020
This work is done as a part of the project - 'Low-cost Decentralized Sanitary System for Treatment, Water and Resources Recovery (Phase 2 of RTC)'.
Objectives of the Project:
To provide a public toilet with a payment system capable to accommodate 50 users per day.
To ensure automation of feces transport without direct handling.
To manage odors via a system of vents and chimney.
Computational fluid dynamics simulation for odor control:
Software applied: Star CCM+
Mesh Generation: Three dimensional mesh generation with base size 0.05 m
Meshing models: Prism Layer mesher, Surface Remesher, Trimmer
Solvers: Gas, Implicit Unsteady, Segregated Flow, K-Omega Turbulence
Inputs: Velocity inlets– Inlet 1 : 25.2 km/h, Inlet 2 & 3 both: 14.4 km/h, Outlets: Pressure outlets, Constant parameters: software default
Simulation Results are captured after 10 sec of reaching full phase. The air is circulating effectively inside the entire fluidndomain and venting through the chimney.
