Direct numerical simulations of turbulent pipe flow power-law fluids at $Re_{\unicode[STIX]{x1D70F}}=323$ are analysed in order to understand the way which shear thinning or thickening affects first- and second-order statistics including kinetic energy production, transport dissipation such flows. The results show that with thinning, near-wall streaks become weaker axial azimuthal correlation lengths velocity fluctuations increase. Viscosity give rise an additional stress term mean momentum...
An adaptation of the work by Huber and Muller on partial transmit sequences (PTSs) for reduction peak-to-average power ratio (PAPR) in orthogonal frequency division multiplexing (OFDM) is described. The new variation combines cyclic shifts inverse fast Fourier transform (IFFT) sub-block output with PTSs. performance scheme slightly better than that a PTS same number comparisons avoids need complex multipliers when phase rotations greater 4.
Direct numerical simulations of turbulent pipe flow power-law fluids show that the effect shear thinning on turbulence statistics in inner-wall region does not disappear as Re is increased. A log-law mean viscosity profile also predicted self-similar inner region.
Abstract Applying Onsager's theory in one dimension it is shown that there a finite probability for carrier to escape geminate recombination with its image charge t the interface of molecular crystal and metal even absence an external field. In contrast three dimensional case, however, not strictly linear function field depends on initial pair separation, at low fields. Good agreement between experiment obtained.
Abstract
Thermal decomposition of bis 2-amino-5-phenyl-1,3,4-thiadiazole copper(II) sulphate has been studied by TG, DTA and DTG. The electrical conductivity the compound in solid state have also measured at different temperatures. It is believed that a nucleation controlled process starts site defects.
