Endwall fillet and bulb structures are proposed in this research to improve the temperature uniformity of pin-fined microchannels. The periodical laminar flow and heat transfer performances are investigated under different Reynolds numbers and radius of fillet and bulb. The results show that at a low Reynolds number, both the fillet and the bulb structures strengthen the span-wise and the norma...

the premature breakage in some four cylinder diesel engine crankshafts was reported. all crankshafts were failed from the same region. failures had occurred in the first crankpin, the nearest crankpin to the flywheel. dynamic analysis and finite element modelling were carried out to determine the state of stress in the crankshaft. fem results revealed that the first crankpin fillet is the most ...

T-joint fillet welds are a very common occurrence found in industry today. Localized heating and cooling from the welding process lead to the rise of distortion and residual stresses. Weld fixturing is a common practice in industry used to address the problems associated with welding, however fixturing also creates problems of residual stresses being locked into the weldment. This research invo...

This study examined the effects of stocking density on live performance, physiological stress level indicators, and processing yields of male broilers grown to 1.8 kg. A total of 3,120 Ross x Ross 708 male chicks was placed into 32 floor pens (5.57 m2/pen). Stocking density treatments were 25, (75 birds/pen), 30 (90 birds/ pen), 35 (105 birds/pen), and 40 (120 birds/pen) kg of BW/m2. The BW gai...

The material reduction factor of rectangular hollow section (RHS) joints in a new version Eurocode 3 part 1–8 is validate for steel with the nominal yield strength up to 700 MPa. In this paper, finite element simulations gap K-joints are conducted investigate effects properties, size joint, brace chord width ratio and welds type on secondary bending stresses resistance. governing failure mode c...
