ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.Material science advances show how surface chemistry improves low‐temperature prepared TiO2‐SiO2 composite films. Using a colloidal‐based synthesis method instead of a powdered‐based one, researchers exploit hydroxyl groups' interfacial interactions to create nanoscale structures with superior physicochemical and mechanical stability.

MIXED CONVECTION AT A STAGNATION POINT
The Quarterly Journal of Mechanics and Applied Mathematics, 1995Summary: We are concerned with the mixed convective flow at a two-dimensional stagnation point on a heated horizontal boundary. The forced flow may be a stagnation-point flow of either forward or rear type, and the free convective element is due to a pressure gradient that is induced by temperature variations along the boundary.

Proceeding of Proceedings of CONV-14: International Symposium on Convective Heat and Mass Transfer. June 8 - 13, 2014, Kusadasi, Turkey, 2014
This lecture aims to place again the mixed thermal convection in the center of the convection heat transfer and to emphasize three issues that arise by this approach: (i) a clear definition of the reference temperature in the Boussinesq approximation; (ii) a practical delimitation of the three convective modes, which are the forced convection (FC ...

Mixed convection in a periodically heated channel
Journal of Fluid Mechanics, 2015Mixed convection in a channel with flow driven by a pressure gradient and subject to spatially periodic heating along one of the walls has been studied. The pattern of the heating is characterized by the wavenumber${\it\alpha}$and its intensity is expressed in terms of the Rayleigh number$\mathit{Ra}_{p}$. The primary convection has the form of counter-

Thermal nonlinear oscillator in mixed convection
Physical Review E, 2011A detailed numerical simulation is carried out for transient laminar flow opposing mixed convection in a downward vertical channel flow with both walls suddenly subjected to isothermal heat sources over a finite portion of the channel walls, by solving the unsteady two-dimensional Navier-Stokes and energy equations. The dynamical behavior of the system

One-dimensional mixed MHD convection
International Journal of Heat and Mass Transfer, 2006The parallel, fully developed flow of an electrically conducting fluid between plane parallel walls under the simultaneous influence of a driving pressure head, buoyancy, and magnetohydrodynamic (MHD) forces is studied. The fluid is assumed to be internally heated and the flow is modeled as one-dimensional and incompressible, while the Boussinesq ...

Optimal Spacings for Mixed Convection
Journal of Heat Transfer, 2004This paper completes the description of geometry optimization in stacks of parallel plates that generate heat. The spacing between plates, or the number of plates in a fixed volume, has been maximized in two limits: pure natural convection and pure forced convection. In this paper, the in-between regime of mixed convection is modeled numerically. After

Abstract A proper mixed convection parameter ζ = (σ Ra) 1 5 (ω Re) 1 2 , with σ = Pr (1 + Pr) and ω = Pr (1 + Pr) 1 3 , is proposed to replace the conventional parameters, Gr Re 5 2 and Re Gr 2 5 , for the analysis of mixed convection wall plumes.
