个人简介
Dr. Fernando Z. Sierra Espinosa is a Mechanical Engineer by the National University of Mexico, UNAM in 1985. He started as a researcher working on hydrodynamics of doubly diffusive systems, and obtained the diploma in alternate sources of energy in SOGESTA, Italy in the same year. Subsequently, he joined the electrical Research Institute México, to investigate the hydrodynamics of solar ponds, until getting involved in an MSc program in thermal engineering with the University of Salford, England. In his thesis, he proposed the energy stored in a solar pond for thermal activation of an absorption refrigerator. Dr. Sierra Obtained his PhD degree from the University of Wales College of Cardiff, United Kingdom, in 1998. His study on turbulence in T junction pipes focused on the problem of the separation of the boundary layer and recirculating flows. The experiments were based on the use of lasers to measuring fluid velocity: LDA and PIV, and supported by numerical predictions. He applied numerical and experimental work to convective flow, transition to turbulence and interaction of magnetic fields using conductive fluids on flat and undulating walls, at UNAM. He joined the Morelos State University, at CIICAp, in 2002 introducing computational fluid dynamics, CFD, LDA and PIV, for the study of turbulent flows in turbines. These techniques have been adopted by several researchers in the CIICAp.
Some topics resolved until now have been erosion in materials exposed to the flow of steam turbines; turbulence and chemical reactions in combustion chambers, turbulence and concentration in stirred mixtures; multiphasic separators and recently in cooling techniques in gas turbines blades; he applied predicted and measured data to conduct failure analysis of combustion and rotor elements of turbines using modal analysis, spectroscopy analysis and statistics. In collaboration with other academic bodies of the CIICAp conducted studies of dynamics of fluids in channels and its effect on the electrochemistry of reactors; and lately it has used the same techniques to study the heating of coffee beans during roasting, as well as the effects of bubbling in reactors type column.
Dr. Sierra was invited by the National Center of Technological Development of Mexico, Cenidet, to study the currents of air in rooms looking for thermal comfort using passive architecture based on the use of wind towers for forced convection.
Recently, he proposed power generation using the rate of deformation at the tires of a car during its motion, and the stirring of mixtures by rotating a cylinder; both problems are industrial applications. He also was granted one patent on the automobile generator of electricity based on tire strain stress. As head of the Laboratory of Fluid Mechanics of the CIICAp, Dr. Sierra created experimental infrastructure, implementing the anemometry PIV and laser Doppler, LDA, as well as built the frequently used wind tunnel which hanless hot and cold air streams.
He has directed seven projects on Mechanical Engineering Science and its applications, financed by CONACYT, by the Federal Utility Commission, CFE, and the program PROMEP. Likewise, he maintains collaborations with Texas A & M Professor J.C. Han; with University of Cardiff, U.K. Professor Phill Bowen.
Dr. Sierra has been granted one Patent in electricity generation based on tire deformation and stress during movement.
He supervised and graduated twelve PhD students, twenty one MSc and eigth BSc graduates, and was lecturer in the subject Fluid Mechanics, Fluids and Heat, Laboratory of Heat Transfer, Transport Phenomena, Computational Fluid Dynamics, Laboratory of Fluids, and Turbulence in Fluids to postgraduate and undergraduate levels. Also, he advised other PhD students and was part of forty graduate and undergraduate theses reviewing boards.
In academic management Dr. Sierra has served as Coordinator of Mechanical Engineering area in Posgraduate Program, CIICAp; titular and substitute in the Academics Technical Council, CIICAp. He is reviewer of articles for indexed journals like Heat and Mass Transfer and J. of Applied Thermal Engineering. Dr. Sierra has coauthored 98 papers; many of them are in indexed journals (SCI), have received 607 cites as by Scholar.google; and he is the first author or author's correspondence in 47%; He is member of the National System of Researchers, SNI, Mexico, pointed up to Level II/III since 2014.
In summary, Dr. Sierra has contributed to the analysis of fluid flow and heat exchange to:
• turbine blade film cooling;
• absorption refrigeration;
• turbulence modelling of boundary layer separation and vibration effects in pipe flow;
• stress distribution and interaction fluid-solid surface;
• swirl combustion;
• flow and heat transfer in buildings;
• mixing, separation and water treatment by Taylor-Couette vortex flow;
• coffee roasting process;
• and design of electrochemical parallel plate reactors.
