Numerical Computation of Turbulent Flow Fields in a Fan-stirred Combustion Bomb

This work presents a numerical study of the initial turbulent flow characteristics prior to ignition in a fan-stirred combustion vessel. The moving mesh methodology has been applied to account for the rotational movement of eight fans mounted within the vessel. The transient, highly-resolved numerical simulations resolve the 3D turbulent flow field in the whole vessel and complement 2D measurements of the flow field. The calculated turbulence...
