Experimental and numerical investigation of gas diffusion under …

This experiment used CO 2 as the tracer gas to test the air volume flow rate. Two CO 2 sensors (Telaire T6615, GE Inc., USA) were fixed at the inlet and outlet of the mockup, and the sensor accuracy was ±% of the maximum value or ±75 ppm of the reading. CO 2 was also used to mimic the leakage gas. Since the principal component of natural gas is CH 4, its density is less than that of air, while the …
