Analysis of Over-Pressure Explosion in a Closed T-Structure Branch Pipe Flowing Different Fuel Mixture

Abstract

In present analysis the T branch shaped pipe was used with three materials steel, mild steel and aluminium to create T branched pipe edges were chamfered in different angles i.e. 30, 60, 45, 72 degrees the lean mixture of gasoline was set to be flow inside the pipe, sensors were attached in on pipe to analyse the effect of over pressure.

From this analysis it was found that mild steel pipe with 60 degree chamfered weld nugget has ability to resist higher over pressure compared to steel and aluminium, the numerical investigation was performed by using computational fluid dynamics analysis in fluent 15.0 domain for mild steel with 60 degree chamfered nugget weld the overpressure value converges the experimental values.
