This study examined the temperature distribution during rotation welding process using birch (Betula spp.) wood dowel and Chinese larch (Larix gmelinii) substrates. Wood dowels were divided into two categories including an untreated group and a group pretreated with cupric chloride. The mechanics test results indicated that the pullout resistance of the pretreated group with welded time 3 s showed...
The reduction of particulate matter (PM) emission from Diesel engines is an important challenge due to their adverse effects on human health and environment. Therefore, Diesel particulate filters (DPF) are used to trap PM in the gas exhaust lines. DPF must be regenerated periodically by burning off the PM deposit in order to prevent high back pressure level. It is well known that Balance Point Temperature...
Through the DPF regeneration experiment with the DPF inlet temperature slowly increased, the balance point temperature of DPF and pressure-drop characteristics with temperature change in the DPF regeneration process have been determined. Obtained from the experiment, with the DPF inlet temperature increasing, particle oxidation rate is greater than the loading speed, and the DPF pressure-drop decreases...
The process of solidification of continuous casting of thin slab on compact strip production (CSP) was simulated by finite element method (FEM) and two-dimensional cutting slice method. Simulated results of solidification and heat transfer of the slab were gotten. The temperature distribution of the cooling process on the thin casting slab is agreed with the actual online production. Influence of...
A three-dimensional heat transfer model was developed to simulate the temperature distribution of the cooling copper mould used in the thin slab continuous casting process. Temperature field of the copper plate of the funneled mould was calculated by finite element method (FEM). It was confirmed that the simulation results are in agree with the experiments and actual online production. Influences...
