Mialdun, A. ; Sechenyh, V. ; Legros, J. C. ; Ortiz de Zárate Leira, José María ; Shevtsova, V. | American Institute of Physics | 2013-09-14We present a comprehensive analysis of experimental results obtained for Fickian diffusion in the benchmark ternary liquid mixture of 1,2,3,4-tetrahydronaphthalene, isobutylbenzene, and dodecane (nC(12)) with equal mass fractions. Isothermal dif[...]texto impreso
Li, W. B. ; Zhang, K. J. ; Sengers, Jan V. ; Gammon, R. W. ; Ortiz de Zárate Leira, José María | American Institute of Physics | 2000-05-22We have performed light-scattering measurements in dilute and semidilute polymer solutions of polystyrene in toluene when subjected to stationary temperature gradients. Five solutions with concentrations below and one solution with a concentrati[...]texto impreso
Ortiz de Zárate Leira, José María ; Fornés, José Antonio ; Sengers, Jan V. | American Physical Society | 2006-10In this paper we evaluate the enhancement of nonequilibrium concentration fluctuations induced by the Soret effect when a binary fluid layer is subjected to a stationary temperature gradient. Starting from the fluctuating Boussinesq equations fo[...]texto impreso
Ortiz de Zárate Leira, José María ; Luis Hita, Jorge ; Khayet Souhaimi, Mohamed ; Legido, José Luis | Elsevier | 2010-11We measured using the multi-current hot-wire method the thermal conductivity (lambda) of two different clay pastes suitable to be used as peloids The same wire and system was used to measure the lambda of water and the results were compared with[...]texto impreso
Vázquez Peñas, José R. ; Ortiz de Zárate Leira, José María ; Khayet Souhaimi, Mohamed | American Institute of Physics | 2008-08-15We present experimental results of the thermal conductivity of several nanofluids prepared by dispersing nanoparticles of SiO(2) and CuO in water and ethylene glycol at various concentrations up to approximate to 5% in mass fraction. The measure[...]texto impreso
Kirkpatrick, T. R. ; Ortiz de Zárate Leira, José María ; Sengers, J. V. | American Physical Society | 2015-07-14In this Letter, we consider a liquid mixture confined between two thermally conducting walls subjected to a stationary temperature gradient. While in a one-component liquid nonequilibrium fluctuation forces appear inside the liquid layer, nonequ[...]texto impreso
In stationary nonequilibrium states coupling between hydrodynamic modes causes thermal fluctuations to become long ranged inducing nonequilibrium Casimir pressures. Here we consider nonequilibrium Casimir pressures induced in liquids by a veloci[...]texto impreso
Kirkpatrick, T. R. ; Ortiz de Zárate Leira, José María ; Sengers, Jan V. | American Physical Society | 2016-03-11In this article we derive expressions for Casimir-like pressures induced by nonequilibrium concentration fluctuations in liquid mixtures. The results are then applied to liquid mixtures in which the concentration gradient results from a temperat[...]texto impreso
In this paper we investigate intrinsic thermally excited nonequilibrium velocity fluctuations in laminar planar Couette flow. For this purpose we have complemented the solution of the stochastic Orr-Sommerfeld equation for the intensity of the f[...]texto impreso
Giraudet, Cédric ; Bataller, Henri ; Sun, Yifei ; Donev, Aleksander ; Ortiz de Zárate Leira, José María ; Croccolo, Fabrizio | European Physical Society | 2015-09Fluctuations in a fluid are strongly affected by the presence of a macroscopic gradient making them long- ranged and enhancing their amplitude. While small-scale fluctuations exhibit diffusive lifetimes, moderate-scale fluctuations live shorter [...]texto impreso
La Biblioteca Histórica de la Universidad Complutense, bajo la signatura BH MSS 205, custodia un manuscrito antiguo con material diverso en latín y castellano atribuido a Diego Pérez de Mesa, que fue catedrático de Matemáticas en la Complutense [...]texto impreso
We present a study of the spatial correlation functions of a one-dimensional reaction-diffusion system in both equilibrium and out of equilibrium. For the numerical simulations we have employed the Gillespie algorithm dividing the system into ce[...]texto impreso
Martín Gallego, Mario ; Verdejo, Raquel ; Khayet Souhaimi, Mohamed ; Ortiz de Zárate Leira, José María ; Essalhi, Mohamed ; López Manchado, Miguel Ángel | Springer | 2011-12-01We employed an easy and direct method to measure the thermal conductivity of epoxy in the liquid (nanofluid) and solid (nanocomposite) states using both rodlike and platelet-like carbon-based nanostructures. Comparing the experimental results wi[...]texto impreso
Compositional grading within a mixture has a strong impact on the evaluation of the pre-exploitation distribution of hydrocarbons in underground layers and sediments. Thermodiffusion, which leads to a partial diffusive separation of species in a[...]texto impreso
We present an analysis of the transverse-velocity fluctuations in an isothermal liquid layer with a uniform shear rate between two parallel horizontal boundaries as a function of the wave number and the Reynolds number. The results were obtained[...]
