Kirijen is a Lecturer in Aerospace Engineering. He is also research active in the areas of aerospace, mechanical and medical engineering. His area of research expertise is in Multicomponent Multiphase flow using Computational Fluid Dynamics (CFD) such as droplet transport, contact-angle, solid-liquid interaction, liquid-liquid interaction, complex rheology effects, adhesion tests and peel tests.
He teaches Aeromechanics, Aerospace vehicle, Computational modelling and Individual project supervision for third year students. Also the placement year tutor for Aerospace engineering students.
Kirijen completed his PhD at the school of mechanical engineering at the University of Leeds. His PhD research was on computational modelling of coalescence filtration process, he closely worked with Parker Hannifin company and created a computational modelling (Lattice Boltzmann method) code to analyse the coalescence effect. The simulation was validated with past research and theories.
