In this paper, the problem of turbulent forced convection flow of water- alumina nanofluid in a uniformly heated pipe has been thoroughly investigated. In numerical study, single and two-phase models have been used. In single-phase modeling of nanofluid, thermal and flow properties of nanofluid have been considered to be dependent on temperature and volume fraction. Effects of volume fraction a...

High Performance Computing (HPC) can be understood as the interaction of parallel and adaptive methods with fast solvers on powerful parallel computers. Therefore, an introduction to parallel and adaptive methods as well as to fast solvers is given. The interaction of these methods is demonstrated using three examples which deal with groundwater flow and transport processes, gaswater flow as we...

Abstract In this paper, we extend our study of mass transport in multicomponent isothermal fluids to the incompressible case. For a mixture, incompressibility is defined as independence average volume on pressure, and weighted sum partial densities stays constant. type models, velocity field Navier–Stokes equations not solenoidal and, due different specific volumes species, pressure remains con...

the main contribution of the present work is to investigate the capability of exponential-type constitutive equationto model the warm deformation flow curves of a eutectoid steel in the temperature range of 620-770 °c andat the strain rates in the range of 0.01-10 s-1 conducted on a gleeble-1500 thermomechanical simulator. warmdeformation in this temperature range facilitates the occurrence of ...

optimal pricing of public parking can improve parking management. this leads to traffic flow, thereby reduces the cost of transportation network. in this paper, the transportation network with some origins, destinations, and public parking was considered. in the network, private cars drivers depending on travel time between origin and parking (driving time), travel time between parking and dest...

Complementing evidence that childhood poverty negatively affects adult outcomes, the impact of poverty on well-being in late childhood is investigated empirically to help inform the targeting of policy. Child well-being and household poverty are conceptualised as multi-dimensional phenomena and structural equation modelling used to ascertain the relative importance of determinants of child well...
