Summary:

In this paper evidence is presented in support of the concept that an increased face surface area as well as its orientation contributes greatly in favor of radiation energy losses from the core of a Diesel Particulate Filter (DPF) under extreme temperature conditions. This effect is achieved through angling of the inlet and outlet core faces, whereby the face surface area can be manipulated independently of the channel length.The novel technology addresses the problem of uncontrolled regeneration at low flow rates where heat loss through convection is insufficient to prevent temperature spikes. Results of a computational fluid dynamics (CFD) model are presented in which peak core temperatures and heat absorption capacity of angled and non-angled core face configurations are compared
