A comprehensive model has been proposed to account for the large enhancement of thermal conductivity in nanofluids and its strong temperature dependence, which classical Maxwellian theory unable explain. The dependence on particle size, concentration, taken care simultaneously our treatment. While geometrical effect an increase surface area with a decrease rationalized using stationary model, accounts enhancement, moving developed from Stokes-Einstein formula explains effect. Predictions...

This paper highlights an investigation on the comparative analyses of exergetic performance with optimum volume concentration hybrid nanofluids in a plate heat exchanger (PHE). Different types (Al2O3 + MWCNT/water, TiO2 ZnO and CeO2 MWCNT/water) as coolant have been tested. Proportion 0.75% nanofluid has found to be concentration. The requisite thermal physical properties were measured at 35 °C. Various parameters examined for comparing different nanofluids. highest reduction exergy loss...

A muffler designed to have high insertion loss would be generally complex, involving cross-flow perforated elements as well absorptive acoustic lining. Side-inlet and/or side-outlet configurations force the waves mean flow through holes in all directions, which rules out usual 1-D plane wave analysis. In low-frequency range of first few firing frequencies a typical engine, representing prominent peaks unmuffled sound pressure level, distributed can approximated 0-D or lumped elements....

Plasma electrolytic oxidation (PEO) is a technique employed to significantly enhance the corrosion and tribological properties of materials by forming an oxide ceramic film on surface material. In this investigation, ZM21 Mg alloy was subjected PEO treatment in silicate phosphate-based aqueous solutions 5grams 10 grams per liter concentrations. The characterized using SEM, profilometer, thickness meter, polarization test. Results showed that obtained with 10g/L solution offers higher...

Mufflers are inevitably a significant part of the exhaust systems automobiles for bringing down tail-pipe noise levels. Nevertheless, howsoever well-optimized reasonably large muffler volume be (with respect to insertion loss, back pressure, breakout noise, flow etc.), there acoustic modes present, which lead peaks in levels and corresponding troughs loss (IL) an baseline. These are: (i) internal modes, (ii) axial pipe (iii) system modes. Of these, mode is most detrimental one. Usage...
