The effectiveness of a loader-mounted fan on diesel vehicles combined with natural convection of a dead heading (the patented janelid system) was investigated experimentally. The results were obtained using co2 as a tracer gas in a one-quarter-scale model heading. Bouyant forces were scaled to establish similarity with full scale. For a loader moving in a typical load-haul-dump cycle, the loader-mounted fan reduced the tracer gas concentration by 26 pct compared with a reduction of 32 pct for a jet fan of four times the flow capacity.
