The weak vector and axial-vector form factors have been investigated for the semi-leptonic octet baryon decays in the chiral constituent quark model with configuration mixing (χCQMconfig). The effects of SU(3) symmetry breaking and configuration mixing have also been investigated and the results are not only in good agreement with existing experimental data but also show improvement over other ...

This paper presents a cold flow simulation study of a small gas turbine combustor performed using laboratory scale test rig. The main objective of this investigation is to obtain physical insight of the main vortex, responsible for the efficient mixing of fuel and air. Such models are necessary for predictions and optimization of real gas turbine combustors. Air swirler can control the combusto...

Powder compaction technology has advanced significantly over the past decades and is considered as an alternative lower-cost process to machining, casting, stamping, forging and other similar metal-working technologies. Feedstock preparation is considered a vital step in producing parts through the powder route because any inhomogeneity within the powder mass would cause inhomogeneous density d...

In this work, we investigated the mixing between strange axial vector mesons K1(1270) and K1(1400) by using QCD Sum Rules approach. Since these states couple to same interpolating currents, defined them in terms of orbital angular momentum eigen K1A K1B. By tensor currents which are almost purely coupling K1B, then employing orthogonality physical states, obtained an analytical expression for K...

gas mixing in a t-shape micro mixer has been simulated using the direct simulation monte carlo (dsmc) method. it is considered that the adequate mixing occurs when the mass composition of the species, co or n2, deviates below 1 % from their equilibrium composition. the mixing coefficient is defined as the ratio of the mixing length to the main channel’s height. as the inlet kn increases, while ...

Einstein-Cartan gravity, which is an alternative formulation of general relativity, introduces new degrees freedom contained in the torsion field encodes feature spacetime. Interestingly, couples to all fermions through its axial-vector mode with a universal coupling $\ensuremath{\eta}=1/8$ possible change under quantum effects. We argue that gravity provides significant portal probe ${A}^{\ens...

The influence of dose rate, i.e., ion flux, on ion beam mixing in Nb-Si bilayer samples was measured at room temperature and 325 °C. At the higher temperature, an increase in dose rate of a factor of 20 caused a decrease in the thickness of the mixed layer by a factor of 1.6 for equal total doses. At room temperature, the same change in flux had no effect on mixing. These results are consistent...

An experimental investigation of hydrodynamics gas-solid flow is carried out by engaging different designs air distributor plates. analysis three plates, i.e., perforated, 45° slotted and novel hybrid plate, revealed the difference in pressure drop minimum fluidization velocities (Umf) for varying input operational variables. Umf found to be lowest perforated highest whereas plate plate. The bu...
