This paper examines the impact of hybrid nanoparticles on stagnation point flow towards a curved surface. Silica (SiO2) and alumina (Al2O3) are added into water to form SiO2-Al2O3/water nanofluid. Both buoyancy-opposing -assisting flows considered. The governing partial differential equations reduced set ordinary equations, before being coded in MATLAB software obtain numerical solutions. Findi...

The use of nanoparticles in fuels provides new opportunities for modification fuel properties, which may affect the operational parameters engines, particular efficiency and consumption. paper presents comparison compression ignition engine performance fuelled with neat diesel nano-diesel. Alumina (Al2O3) was used as nanoparticles. Surface-active substances, including Span 80 surfactant, well w...

A computational analysis has been performed for Casson hybrid nanofluid natural convection heat transfer in trapezoidal cavity containing a partially heated at bottom wall, and the incline walls are set to be cold temperature while top wall is supposed adiabatic. The nanoparticles, alumina copper dispersed ethylene glycol water mixture used as working fluid. finite element method solve nondimen...

High surface area alumina-supported cobalt oxides and carbides were synthesized using a one-pot reverse microemulsion method (followed by carburization for carbides). Two synthesis variations gave fine powders having specific areas ranging from 178−272 m2/g, consisting of oxide or carbide nanoparticles (5−10 nm) dispersed on γ-alumina (10−13 wt% loadings). The resulted materials tested CO2 hydr...

PURPOSE The purpose of the present study was to evaluate the flexural strength of the joint between glass-infiltrated alumina frames and the experimental adjusting agent (MA modifier) that contains alumina and magnesia. METHODS A commercially available adjusting agent (Optimizer), a slurry of alumina powder (Alumina modifier), and a bulk specimen (joint-free alumina) were used as controls. Be...
