Special Issue Information

Dear Colleagues,

Microfluidics (or lab on a chip) and microscale flow and heat/mass transfer are areas of research that have continuously expanded and flourished over many years. These areas are linked to a variety of applications in biology, chemistry, pharmacy, microelectronics, and heat transfer engineering, among many others, and have been powerful in unprecedented ways. Along with acquiring a more in-depth understanding of complex fluids and multiphase flows, increasingly more new functionalities in microfluidic devices and microscale flow and heat/mass transfer techniques are being invented. Meanwhile, the relevant techniques for conducting research in these areas, both experimental and numerical, are also being developed.

We are inviting submissions for a Special Issue of Energies “Microfluidics and Microscale Flow and Heat/Mass Transfer”, which is dedicated to the abovementioned subject areas. With this Special Issue, we expect to compile the latest developments in these and related areas, especially applications of complex fluids (normally non-Newtonian) or multiphase flows in microfluidics and thermal fluid sciences at micro or nanoscopic scale. Specific topics of interest for this Special Issue include, but are not limited to:

  • Multiphase flows (with heat/mass transfer) in microchannels or microfluidic devices;
  • Non-Newtonian fluid flows (with heat/mass transfer) in microchannels or microfluidic devices;
  • Heat transfer enhancement techniques at microscale;
  • Phase change heat transfer at microscale.
  • Experimental methods and measurements in microchannel flows (with heat/mass transfer) or microfluidic devices;
  • Numerical methods and simulations related to microchannel flows (with heat/mass transfer) or microfluidics.

To improve the performance of a high-pressure refueling liquid oxy-kerosene engine, the influence of drag-reducing additive on the heat transfer characteristics in the supercritical flow of kerosene in a microchannel for regenerative cooling is explored. The finite-volume CFD numerical simulation method is applied using the RNG k-ε turbulence model and enhanced wall function. The current work faithfully represents the effect of the drag-reducing additive in kerosene through numerical calculations by combining a 10-component model for the physical properties of the kerosene and the Carreau non-Newtonian fluid constitutive model from rheological measurements. Results suggest that the 10-component kerosene surrogate can describe the supercritical physical properties of kerosene. The inlet temperature, inlet velocity, and the heat flux on the channel wall are driving factors for the supercritical kerosene flow and heat transfer characteristics. The pressure influence on the heat transfer is negligible. With polymer additives, the loss in pressure drop and heat transfer performance of supercritical kerosene flow decrease 46.8% and 37.5% respectively. The enhancement of engine thrust caused by reduction in pressure drop is an attractive improvement of concern. Full article
