Honorary Member

Prof. Clovis R. Maliska

Prof. Maliska is devoted to the development of numerical methods for the solution of Navier Stokes and Darcy's equations using the EbFVM-Element-based Finite Volume Methods with hybrid unstructured grids. Applications for petroleum reservoir simulation and reservoir/well coupling are key activities. Recently he is developing a new methodology for solving geomechanics coupled with fluid flow using for both physics the finite volume technique (EbFVM) with a single unstructured grid. This approach simplifies considerably the coupling problem and alleviates the pressure oscillations.

Personal Profile

Prof. Maliska earned his Ph.D. from the University of Waterloo, Canada, with emphasis in the solution of the Navier-Stokes Equations using curvilinear coordinate systems. Back to his University in Brazil he founded the SINMEC- Computational Fluid Dynamics Laboratory and started cooperation with the local industries, especially Petrobras and supervision of Master and Ph.D. students.

He was member of several Brazilian Committees on Science and Engineering, being the most important the Committee for Mechanical, Aerospace and Naval Engineering  of  National Council of Research – CNPq. This committee, chosen by the voting of the scientific community annually analysis and grants the funds for projects applied by the Brazilian researchers.  He took part on this Committee for three mandates of 3 years each. He was President of the national Committee of the Coordinators of the research projects funded by ANP – National Agency for Petroleum and Bio Fuels.

He is involved with research activities with Petrobras for more than 25 years in the area of Petroleum Reservoir Simulation, including well/reservoir coupling, development of numerical schemes and development of libraries for code creation with unstructured grids. His team of research created the EFVlib, a computational package using hybrid grids (tetras, prisms, hexas and pyramids), for the development of porous media flow in reservoirs. Recently he is developing algorithms using unstructured grids for solving the geomechanics and fluid flow using for both physics the EbFVM – Element-based Finite Volume Method, with the same grid, avoiding interpolation, as usually done when the rock mechanics is solved using finite elements and the fluid flow using finite volumes with different grids. The critical oscillations encountered in this type of problem are also avoided with the methodologies under development. He is the author of the first Brazilian book on CFD: “Computational Heat Transfer and Fluid Flow” (in Portuguese) used by most of the graduate programs in Mechanical Engineering in Brazil. The book is now being updated and the 2004 edition is available as an e-book at www.grupogen.com.br.

Perhaps the most significant contribution was to help the creation of ESSS – Engineering Simulation and Scientific Software, a company also member of TechNet Alliance, which was a spin-off company of his laboratory SINMEC.
 

Career and Current Position

He is a Mechanical Engineer and Master of Science by the Federal University of Santa Catarina, and earned his Ph.D. in Mechanical Engineering at the University of Waterloo, Canada, focused on numerical techniques for the Navier-Stokes equations. He is a full professor and leader of the SINMEC, Computational Fluid Dynamics Lab. He supervised more than 20 Ph.D. and 40 Master students with more than 200 conferences and journal papers.

He is referee of several national funding agencies, like FINEP, FAPESP, FAPERJ, CAPES, CNPq.

Currently he is a Full Professor of the Mechanical Engineering Department of the Federal University of Santa Catarina.
