Bifurcation Diversity in an Annular Pool Heated from Below: Prandtl and Biot Numbers Effects

Torregrosa, A. J.; Hoyas, S; Pérez Quiles, María Jezabel; Mompó Laborda, Juan Manuel (Global Science Press, 2013-02)

In this article the instabilities appearing in a liquid layer are studied numerically by means of the linear stability method. The fluid is confined in an annular pool and is heated from below with a linear decreasing ...
Direct numerical simulation of thermal channel flow for medium¿high Prandtl numbers up to Re_tau = 2000

Alcántara-Ávila, Francisco; Hoyas, Sergio (Elsevier, 2021-09)

[EN] A new set of DNS of a thermal channel flow have been conducted for friction Reynolds and Prandtl numbers up to 2000 and 10, respectively, reaching the Prandtl number of water, 7, for new Reynolds numbers, never simulated ...
DNS of thermal channel flow up to Re-tau=2000 for medium to low Prandtl numbers

Alcántara-Ávila, Francisco; Hoyas, S.; Pérez Quiles, María Jezabel (Elsevier, 2018)

[EN] Direct Numerical Simulations of turbulent heat transfer in a channel flow are presented for three different Reynolds numbers, namely Re-tau = 500, 1000 and 2000. Medium and low values of the molecular Prandtl number ...
Experiments on subcooled flow boiling in I.C. engine-like conditions at low flow velocities

Torregrosa, A. J.; Broatch, A.; Olmeda, P.; Cornejo, O. (Elsevier, 2014-01)

[EN] Subcooled boiling flow is specially attractive for engine cooling system design, as no essential changes in its architecture are required while it is still possible to take advantage of the highest rates of heat ...
Influence of the computational domain on DNS of turbulent heat transfer up to Re-tau=2000 for Pr=0.71

Lluesma-Rodriguez, F.; Hoyas, S.; Pérez Quiles, María Jezabel (Elsevier, 2018)

[EN] We present a new set of direct numerical simulation data of a passive thermal flow in a turbulent plane Poiseuille flow with constant Prandtl number Pr = 0.71, and mixed boundary conditions. Simulations were performed ...
