Buoyancy Driven Heat Transfer of Nanofluids in a Tilted Enclosure
TL;DR: In this paper, the authors investigated buoyancy driven heat transfer of water-based nanofluids in a differentially heated, tilted enclosure, and the governing equations were solved using the polynomial differential quadrature method for an inclination angle ranging from 0 deg to 90 deg, two different ratios of the nanolayer thickness to the original particle radius (0.02 and 0.1), and a Rayleigh number varying from 104 to 106.

Thermal convection in a horizontal fluid layer with uniform volumetric energy sources
TL;DR: In this article, the authors measured energy transport at Rayleigh numbers up to 675 times the critical (linear stability theory) value in a layer of dilute electrolyte bounded horizontally by two rigid planes of constant and equal temperature; Joule heating by an alternating current passing horizontally through the layer provides the volumetric energy source.
