“…Vishwakarma et al [9] investigated the effects of double chamber connection structure on maximum explosion pressure Pmax, the maximum rate of pressure rise (dp/dt)ex and explosion index KG. The results demonstrated that the connection of two chambers led to an increase in the contralateral Pmax.…”

In order to investigate explosive properties of ethylene-air premixed gas in flameproof enclosure with interconnected structure under pressure piling, a 161.5 mm × 161.5 mm × 250 mm cylindrical flameproof enclosure and a 161.5 mm × 161.5 mm × 500 mm cylindrical flameproof enclosure connected by a partition with a hole (inner diameter of 15 mm) were studied. A mathematical model of the fluid dynamics combustion reaction was selected to perform numerical simulations of this structure using the finite volume method. Numerical simulations revealed that under pressure piling, the maximum explosion pressure in Cavity B was significantly higher than that in Cavity A; the maximum rate of explosion pressure rise in Cavity B was significantly higher than that in Cavity A; combustion rate of combustible gas in Cavity B was much higher than that in Cavity A. Results of the study have practical and theoretical significance for the design and installation of flameproof enclosures.

Flameproof (Ex d) enclosures are constructed in such a way that an internal ignition of a flammable atmosphere will not be transmitted outside the enclosure and thereby preventing the ignition of surrounding flammables. The large Ex d enclosure was designed for gas group IIB explosive atmosphere with the help of MATLAB and ANSYS software and further a study of stress analysis due to internal pressure had been carried out on the plates and cover by keeping the thickness of body plate and cover constant. The study showed that stress was observed more in the center of the plate and reducing toward the edges of plates. The value of the length and breadth ratio (a/b) was found out with the help of the curve fitting method to calculate maximum stress (σmax) in the designed Ex d enclosure. The calculated maximum stress of all the plates was less than the simulated results, so the simulated results indicated that the designed enclosure is within the safety limit and suitable for hazardous area.
