Experimental study on deflagration characteristics of non-uniform oil mist in an enclosed chamber

Case Studies in Thermal Engineering, 2023
The deflagration characteristics of oil mist in the marine enclosed chamber are studied. The results show that oil mist deflagration in a non-uniform enclosed chamber is a violent process. When the nozzle size is 1.0 mm, the maximum oil mist deflagration
