CFD Role in Understanding Mixing Processes
Abstract
Computational Fluid Dynamics (CFD) has helped the design and understanding of many industrial processes. This talk will focus on the role that CFD has played in Mixing, the main research area of Dr. Oldshue, whose memory is honored in this lecture. Some practical examples will be shown, and a more detailed description of two works described in the literature will be discussed: 1. A methodology where an optimization method is coupled to a CFD-based methodology to design a new impeller for solid suspension, and 2. A methodology to obtain a Nusselt equation for the heat-transfer coefficient in jackets and internal coils with the use of CFD without any experimental data. These two examples will illustrate the impact that CFD has had in the understanding and prediction of important stirred tank design data. The methodology to obtain the Nusselt number equation with the use of CFD is compared with the classical experimental work of Oldshue and Gretton (1954) for tanks heated (or cooled) with internal helical coils. The final Nusselt correlation was compared with all the 107 experimental points of the work by Oldshue and Gretton (1954), with an average deviation on the results of 10.7 %.
Prof. José Roberto Nunhez
Prof. Nunhez was a Consultant in Brazil for TOTAL Paris working for the Direction Scientifique in Paris during the years 2013 and 2014. He has consulted for several Chemical and Petrochemical industries. His group developed an in-house three-dimensional CFD model to study soluble effluent dispersion in rivers, which has been used in consulting works to evaluate the environmental impact of industries effluent emissions in river sections. He has also organized and ministered several courses on Mixing that is mainly attended by industry professionals.
Prof. Nunhez has been recipient of several awards, including advisor of the best PhD thesis in Brazil in 2006, according to the Brazilian Society of Chemical Engineers (ABEQ). He was the main organizer of the SYMPOSIUM ON CFD IN CHEMICAL ENGINEERING AND INDUSTRIAL PROCESSES at the 8th WCCE (World Congress of Chemical Engineering) held in Montreal in 2009. He was the Guest Editor of Volume 89, 4th issue of the Canadian Journal of Chemical Engineering, which published a Special Issue Section with papers presented at the CFD Symposium at the 8th WCCE. He is also the main organizer of the Symposium CFD IN CHEMICAL ENGINEERING: CHEMICAL PROCESSES, EQUIPMENT DESIGN AND OPTIMIZATION, at the 10th WCCE, to be held on October 1-5, 2017, in Barcelona, Spain.
James Y. Oldshue Lecture
This lecture was jointly established in 2008, in memory of James Y. Oldshue by the American Institute of Chemical Engineers (AIChE) and the Inter-american Confederation of Chemical Engineering (CIIQ/IACChE).
Jim Oldshue was an important leader and supporter of the CIIQ/IACChE. He was President of the AIChE in 1979 and President of the CIIQ/IACChE in 1995. Jim was a recipient of the prestigious Víctor Márquez award in 1983, which is conferred by the CIIQ/IACChE. Jim was an ambassador of the profession who visited more than 100 countries. It is envisioned that this lecture provide a global perspective of a specific contingent topic. The Oldshue Lecture alternates between the AIChE Annual Meetings and the Interamerican Congresses, which take place every two years.
