Abstract
Non-homogeneous mixing of methane (NHM) within closed chambers was studied under laboratory conditions. The experimental set up consisted of a PVC vented chamber of 5.3 litres of effective volume implemented with a power-adjustable 12V fan. NHM was addressed by injecting a known volume of methane and extracting, afterwards, gas samples from the top, middle and bottom sections of the chamber. NHM within the chamber was studied under different experimental situations such as the fan position (top ...
