Heat Transfer by Forced Convection
Proceedings of the Physical Society, 1959Heat transfer between a solid (metal sphere) and a fluid in forced convection at higher Reynolds numbers was studied. The relation between heat transfer, friction-drag force, and drag coefficient was established and the values of drag coefficient are exhibited for different Reynolds numbers.

Forced-convective vitrification with liquid cryogens
Cryobiology, 2013Cell cryopreservation by vitrification generally requires using vitrification solutions with high concentrations of cryoprotectants (CPAs), which are toxic and induce osmotic stresses associated with the addition and removal of CPAs. To increase the cooling rate and reduce the CPA concentration required for vitrification, this study proposed an ...

Thermal Turbulence in Forced Convection
The Physics of Fluids, 1967The role of the Peclét number in forced convection in a fluid layer randomly heated from below is studied experimentally and numerically. The main features of thermal turbulence, especially the intermittency arising from irregular growth of buoyant plumes, are well reproduced numerically.

Hydrodynamic or Forced Convection Voltammetry
2021Similar to the previous chapter (Chap. 3), this chapter includes more advanced electrochemical scenarios to train the student’s ability to handle a wide range of problems. In this topic, the focus is on electrochemical systems that introduce external convection and hydrodynamic factors which add another dimension to electrochemical problems.

This chapter turns to forced convection. Instead of buoyancy forces, forced convection is a mechanism caused by pumps or fans. This concept is explained through a quick primer on fluid mechanics. Then, the chapter defines the heat transfer coefficient. Afterward, it explores the heat transfer correlations for external flow and for turbulent flow of non-

Forced Convection Heat Transfer
2015Convection is the term used for heat transfer mechanism, which takes place in a fluid because of a combination of conduction due to the molecular interactions and energy transport due to the macroscopic (bulk) motion of the fluid itself. In the above definition, the motion of the fluid is essential otherwise, the heat transfer mechanism becomes a ...

Forced convection adsorption cycles
Applied Thermal Engineering, 1998Abstract The convective thermal wave is part of a patented cycle which uses heat transfer intensification to achieve both high efficiency and small size from a solid adsorption cycle. Such cycles normally suffer from low power density because of poor heat transfer through the adsorbent bed.

ADAPTIVE COMPUTATIONS OF TURBULENT FORCED CONVECTION
Numerical Heat Transfer, Part A: Applications, 1998This article presents an adaptive finite element method for solving incompressible turbulent flows with heat transfer. Solutions are obtained in primitive variables using a highly accurate quadratic finite element method on unstructured grids. Turbulence modeling is achieved using the k-e model.

Forced Convection Normal Helium
1986In many applications of cryogenics, cooling is achieved best by confining the fluid to a tube or duct and circulating it through the system in a closed loop. Several aspects of this method distinguish it from immersion cooling in a pool of liquid. First, the fluid characteristics are more variable because the system is not restricted to operation in ...
