Analysis of Air Distribution at Molecular Sieve Vessel In RDE System Based On Fan Flow Rate Variation Using Aerosol Density Testing Facility

Abstract
The Experimental Power Reactor uses the type of pebble bed fuel and helium gas as its primary coolant. Therefore, to maintain and maintain the quality of helium as a coolant in accordance with predetermined requirements helium purification system is designed. One part of the main component of this helium purification system facility that serves to absorb CO2 and CH4 is molecular sieve vessel. FASKERA is a test facility used to measure the density level of aerosols in a space in real time. To optimize the FASKERA's performance, the characterize of its airflow rate distribution is needed. The purpose of this study is to know the airflow rate homogenous distribution in the FASKERA using fluent 6.3. The fan flow rate varied with speed 20 m/s and 25 m/s. Based on the simulation result of CFD that has been done, it can be concluded that the profile the airflow distribution within FASKERA by using a fan air flow rate of 20 m/s resulted in a more homogeneous air flow rate distribution compared to a fan air flow rate of 25 m/s, this is because the resulting drag force area is fewer and the spatial distribution area of the two airflows is evenly distributed in the chamber.
