Publisher Summary This chapter discusses the heat transfer and the hydraulic resistance of single tubes, and the banks of tubes of various arrangements in flows of gases and viscous liquids. The focus is on the important problems of the heat transfer and the hydraulic resistance of tubes, in particular with the heat transfer of single tubes, banks of tubes, and systems of tubes in crossflow. The chapter also highlights the influence of the physical properties of fluids on heat transfer. Extensive experimental data will be analyzed and will include investigations of banks of tubes of various arrangements, and a single tube in crossflow in the range of Prandtl number from 0.7 to 500 and that of Reynolds number from 1 to 2xl0 6 .read more

Drag, turbulence, and diffusion in flow through emergent vegetation
TL;DR: In this article, a model is developed to describe the drag, turbulence and diffusion for flow through emergent vegetation, which for the first time captures the relevant underlying physics, and covers the natural range of vegetation density and stem Reynolds' numbers.

Introduction to Computational Fluid Dynamics
TL;DR: This paper presents a meta-modelling framework for convection-Cartesian grids that automates and automates the very labor-intensive and therefore time-heavy and expensive process of convection itself.

A Correlating Equation for Forced Convection From Gases and Liquids to a Circular Cylinder in Crossflow
Stuart W. Churchill,M. Bernstein +1 more
TL;DR: In this article, a single comprehensive equation is developed for the rate of heat and mass transfer from a circular cylinder in crossflow, covering a complete range of Pr (or Sc) and the entire range of Re for which data are available.

Compact heat exchangers
TL;DR: The third edition of the second edition as discussed by the authors was published in 1964 and contains basic test data for eleven new surface configurations, including some of the very compact ceramic matrices, in both the English and the Systeme International (SI) system of units.

Experiments on the flow past a circular cylinder at very high Reynolds number
TL;DR: For R > 3.5 × 10^6, definite vortex shedding occurs, with Strouhal number 0.27 as discussed by the authors, while for R > 0.7, the vortex shedding rate becomes constant.

On the development of turbulent wakes from vortex streets
TL;DR: In this article, the authors investigated the wake development behind circular cylinders at Reynolds numbers from 40 to 10,000 in a low-speed wind tunnel and found that in the stable range the vortex street has a periodic spanwise structure.

Distribution of local pressure and skin friction around a circular cylinder in cross-flow up to Re = 5 × 10 6
TL;DR: In this paper, the authors measured the local pressure and skin friction distribution around a cylinder and calculated the total drag, the pressure drag and the friction drag, which can be used to define three states of the flow: the subcritical flow, where the boundary layer separates laminarly; the critical flow, in which a separation bubble, followed by a turbulent reattachment, occurs; and the supercritical flow where an immediate transition from the laminars to the turbulent boundary layer is observed at a critical distance from the stagnation point.

Heat transfer and friction in tubes with repeated-rib roughness
TL;DR: In this article, heat transfer and friction correlations are developed for turbulent flow in tubes having a repeated-rib roughness, based on application of a heatmomentum transfer analogy to flow over a rough surface, which was first used by Dipprey and Sabersky for sand-grain roughness.
