An air-kerosene thermal mass coupled turbine blade with kerosene microchannels added to the traditional laminated structure is proposed, and numerical simulations are carried out. The enhanced heat transfer mechanism of studied, influence different temperatures, blowing ratios, solid conductivity on blades analyzed. results show that adding can significantly reduce temperature change cooling ga...

This Investigation aims to study the effect of adding Steel fibers with different volume fractions Vf (o.5, 0.75, and 1% by concrete) aspect ratio 100 on mechanical properties concrete, alsofinding influence petroleum products (Kerosene Diesel) Fiber Reinforced Concrete (SFRC).The experimental work consists two groups: group one specimens (cubes prisms) plain concrete reinforced steel fiber exp...

Creation of a transonic region by means gas fuel burning in supersonic flow with Mach number M = 2 channel variable cross section is studied numerically. The averaged Navier – Stokes equations closed the k-ε model turbulence are solved. created using gas-dynamic pulses throttling jet, which initiates gaseous combustion constant section. (ethylene or kerosene) supplied axially into axisymmetric ...

Various forms of tinea constitute one of the most distressing complications of the more chronic forms of leprosy. Some of these infections seem to flourish because of the hyperhidrotic condition of the skin of the trunk, which compensates the suppression of the sweat function in the limbs. Other forms of tinea appear to prefer the dry epithelium left by old tuberculoid lesions. The back of the ...

In this paper, hydromagnetic natural convection heat transfer in an equilateral triangular enclosure filled with waterand kerosene-based ferrofluids has been analyzed using a two-component non-homogeneous thermal equilibrium model. The enclosure is permeated by an inclined magnetic field of having uniform strength. The effects of Brownian motion and thermophoresis of the nanoparticles are incor...
