Research Profile for Dr. Siva Nadarajah

 

Affiliation:  

Professor, The Mechanical Engineering Department of McGill University (Montreal, Canada).

 

Description of Research:

Nadarajah’s work has primarily been in the aerospace field, and robust computation and design of complex geometries for both steady and unsteady flows. In the past five years, his group has contributed in several areas; p-adaptive high-order methods [1-2], robust solvers for challenging aerodynamic simulations[3], the development of new limiters for unsteady flows [4], extension of the adjoint methods for turbomachinery and unsteady flows [5–9] and optimization for laminar-turbulent flows [10], and the extension of the adjoint method for design cases with large geometry deformation with the introduction of a novel efficient mesh movement scheme [11,12].
