the objective of the present study is the synthesis of mwcnt-tio2 hybrid nanostructures by solvothermal synthesis method with ticl4 as precursor. the heat transfer enhancement due to the use of mwcnt-tio2 nanofluid was investigated. as-prepared hybrid materials were characterized by x-ray diffraction (xrd) and scanning electron microscopy (sem). the results showed that mwcnts were uniformly dec...

This numerical study compares single-phase forced convective heat transfer between two sandwich panels with tetrahedral metallic lattice cores separately fabricated by investment casting and the more cost-effective metal sheet folding method. The numerical model is validated against available experimental data. For a given Reynolds number and core porosity, the results reveal that the brazed sa...

A three-dimensional model, which coupled flow, heat transfer, solidification, solute transport and electromagnetic field, was separately developed for vertical mold curved of billet continuous casting. Therefore, the characteristics disciplinarians macroscopic behavior different types were revealed. The influence stirring (M-EMS) curvature on in investigated detail. results indicate that M-EMS ...
