Surface - temperature and surface - layer turbulence in a convective 1 boundary layer

Analytical Solution of The Laminar Boundary Layer Flow over Semi-Infinite Flat Plate: Variable Surface Temperature

In this paper, the problem of forced convection over a horizontal flat plate under condition of variable plate temperature is presented and the homotopy perturbation method (HPM) is employed to compute an approximation to the solution of the system of nonlinear differential equations governing the problem. This paper provides good supplements to the existing literature and generalizes the previ...

Boundary layer flow beneath a uniform free stream permeable continuous moving surface in a nanofluid

The main purpose of this paper is to introduce a boundary layer analysis for the fluid flow andheat transfer characteristics of an incompressible nanofluid flowing over a permeable isothermalsurface moving continuously. The resulting system of non-linear ordinary differential equations issolved numerically using the fifth–order Runge–Kutta method with shooting techniques usingMatlab and Maple s...

Skin temperature perturbations induced by surface layer turbulence above a grass surface

High-frequency (5 Hz) atmospheric surface layer (ASL) turbulent velocity (u9) and infrared skin temperature perturbations (T9s) were measured above a grass-covered forest clearing and analyzed for cloud free conditions. These measurements were used to investigate mechanisms responsible for the production of large short-lived T9s perturbations caused by rapid excursions in u9. To quantify the ef...

Where is the surface-layer turbulence?

Remote turbulence sensing in the first 100m above ground using lunar scintillation has revealed that the seeing measured by regular site monitors can be over-estimated. This explains the well-known discrepancy between the VLT image quality and the seeing measured by the DIMM at Paranal. The concept of ”site seeing” needs to be critically reviewed, considering strong dependence of this parameter...
