Análisis de la influencia del consumo eléctrico del vehículo en el gasto de combustible bajo diferentes condiciones de conducción.
Presentación de la ponencia realizada en el 8º Congreso de Ingeniería Termodinámica celebrado en Burgos (19 - 21 de Junio), en la cual se presenta un estudio realizado sobre cómo varía el consumo de combustible en un motor ... -
Characterization and thermophysical properties of rutile and alumina nanofluids
The characterization in relation to shape and particle size of alumina and rutile suspensions was performed. The intrinsic viscosity exhibited the presence of nonspherical aggregates in both suspensions although TEM ... -

Legume flours due to their nutritional benefits (e.g., high levels of proteins, fiber, complex carbohydrates, micronutrients and vitamins) are ideal ingredients for improving the nutritional value of bread and bakery ... -
Design and Assessment of Survey in a 360-Degree Feedback Environment for Student Satisfaction Analysis Applied to Industrial Engineering Degrees in Spain
Granados-Ortiz, Francisco-Javier; Gómez-Merino, Ana Isabel; Jiménez-Galea, Jesús Javier; Santos-Ráez, Isidro María; Fernández-Lozano, Juan Jesús; Gómez-de-Gabriel, Jesús Manuel; Ortega-Casanova, Joaquín[et al.] (MDPI, 2023-02-13)
The number of students enrolled in engineering studies in Spain is in decline, mainly due to the difficulty in passing the subjects, whose factors may be linked to the science-related content of the subject, a very demanding ... -
Elaboración y empleo de herramientas normativas como vehículo de innovación docentes en asignaturas técnicas
Presentación de la ponencia en el 8º Congreso Nacional de Ingeniería Termodinámica celebrado en la Universidad de Burgos, la cual se expone la metodología para la realización de suplementos normativos a componentes ... -
Estudio de un Motor Stirling con Absorbedor Interno Alimentado con Energía Solar
Santos-Ráez, Isidro María (Servicio de Publicaciones y Divulgación Científica, 2015)
La importancia de la energía desde un punto de vista socioeconómico es indiscutible, siendo la energía solar una de las fuentes renovables más atractiva e interesante. Dentro de las múltiples aplicaciones del motor Stirling, ... -
Experimental assessment of thermal and rheological properties of coconut oil-silica as green additives in drilling performance based on minimum quantity of cutting fluids
Gómez-Merino, Ana Isabel; Jiménez-Galea, Jesús Javier; Rubio-Hernández, Francisco José; Santos-Ráez, Isidro María (Elsevier, 2022-09-25)
Conventional metal working fluids are prepared from petroleum based mineral oils with toxic, carcinogenic, non- biodegradable and unsustainable additives, which can cause serious environmental contamination and health risks ... -
Heat transfer enhancement using nanofluids in the compression exchanger in a solar Stirling engine
In this paper a improvement in the heat exchange of a solar Stirling engine during the compression phase was studied. The viability of using nanoparticles as ceramic oxide (Al2O3 in water) at different concentrations ... -
Rheological study of the aggregation state of alumina nanofluids
Arjona-Escudero, José Luis; Santos-Ráez, Isidro María; Gómez-Merino, Ana Isabel; Rubio-Hernández, Francisco José (Hernández, M.J., Sanz, T, Salvador, A., Rubio-Hernández, F.J., 2017)
The presence of alumina solid particles in aqueous phase induces a change in the viscosity of the suspension from Newtonian to non- Newtonian flow. Besides, the presence of solid particles is adequate for the use as a heat ... -
Thermophysical and flow properties of coconut oil with silica fumed nanoparticles
Santos-Ráez, Isidro María; Jiménez-Galea, Jesús Javier; Arjona-Escudero, José Luis; Gómez-Merino, Ana Isabel; Rubio-Hernández, Francisco José; Rubio-Merino, Julia; Tamames Rodero, Víctor[et al.] (2019-10-02)
This work is concerned with the rheological and thermal study of silica fumed dispersed in coconut oil. The dispersed phase behave as a non newtonian fluid during the phase change. The addition of nanoparticles complicates ...
