説明
type:text
The effects of gas flow (swirl and squish) and fuel spray jet on local instantaneous heat flux on the piston crown of a small size direct injection diesel engine are experimentally investigated. Under the motoring operation, local heat flux on the piston with a flat crown increases with increasing local swirl velocity; and the local Nusselt number is found to be proportional to R^<0.636gt;_e, where R_e=2πrv_<θ,r>/ν with v_<θ,r> the local swirl velocity at radius r andνthe kinematic viscosity. While for the piston with cavity, local heat flux is strongly influenced by squish flow. Under the firing operation, it is observed that the heat flux at the position where the fuel spray jet collides is mostly determined by the fuel spray jet.
