Effects of geometrical factors on fracture toughness using semi-circular bending type specimens
Het, Kıvanç; Tutluoğlu, Levent; Department of Mining Engineering (2008)
Semi-circular specimens (SCB) under three point-bending which are commonly used for fracture testing of rocks were used here for fracture mechanics tests. A total of 65 specimens were tested by using Ankara andesite rock. Investigations including the effects of initial notch thickness, different loading span ratios (S/R), flattened loading end, and little dimensional variations when preparing the specimens were carried out. Stress intensity factors for specimens with different geometries were computed indiv...
Effects of different bed roughnesses on the characteristics of hydraulic jumps
Velioğlu, Deniz; Tokyay, Nuray; Department of Civil Engineering (2012)
In practice, baffle blocks and sills are commonly being used to stabilize the location of a hydraulic jump and shorten the length of a stilling basin. On the other hand, gravels, corrugations and rectangular prismatic roughnesses which cover the entire length of the basin or placed in a staggered manner may be an alternative. The objective of this study is to determine the effects of these roughness elements on the characteristics of hydraulic jumps such as conjugate depth, jump length and energy dissipatio...
Effects of geometric factors on mode I fracture toughness for modified ring tests
Tutluoğlu, Levend (2012-04-01)
Stress intensity factors of specimen models with various external diameters, inner hole diameters, and extents of flattened loading boundaries for the modified ring testing method for mode I fracture are computed by finite element modeling. Effects of boundary conditions and geometric factors on stress intensity factor computation are analyzed. Parametric expressions are proposed to estimate critical crack length position and corresponding maximum stress intensity factor. An expression in terms of inner hol...
Effects of injection strategies and fuel injector configuration on combustion and emission characteristics of a DI diesel engine fueled by bio-diesel
Maghbouli, Amin; Yang, Wenming; An, Hui; Li, Jing; Shafee, Sina (2015-04-01)
A multi-dimensional computational fluid dynamics (CFD) modeling was conducted on a D.I. (Direct Injection) diesel engine fueled by bio-diesel based on KIVA4 code. Comprehensive chemistry prediction of bio-diesel fuel was taken into account by enhancing the combustion model of the default KIVA4 code. An advanced multi-component fuel combustion model was applied to accurately predict the oxidation of saturated and unsaturated agents of the bio-diesel fuel using a reduced chemical kinetics mechanism. In order ...
