In this paper, second law analysis for calculations of the entropy generation due to the flow andheat transfer of water-Al2O3 and ethylene glycol-Al2O3 nanofluids inside annuli is presented. Thephysical properties of the nanofluids are calculated using empirical correlations. Constant heatfluxes at inner surface of the annuli are considered and fully developed condition for fluid flowand heat t...

near-surface variations can be very complex and may distort amplitudes and arrival times of the reflections events from target reflectors. near-surface complexities include topographic variations, near-surface irregularities, variations in soil conditions and the weathered layer. these perturbations generally have a significant impact on seismic recordings. although there is a general agreement...

We study the properties of various Eulerian contributions to fluid particle acceleration by using well-resolved direct numerical simulations isotropic turbulence, with grid resolution as high $12288^3$ and Taylor-scale Reynolds number $R_\lambda$ in range between 140 1300. The variance convective acceleration, when normalized Kolmogorov scales, increases linearly $R_\lambda$, consistent simple ...
