Kumar Pushpak

I specialize in developing high-performance numerical solvers (OpenFOAM, ANSYS, FEniCS) for complex multi-physics problems, from reentry vehicle aerodynamics to reactive casting processes. My work involves:

Advanced Solver Development: Built computational models for reactive casting simulations, optimizing parameters to evaluate polymer processing efficiency.

Conducted a numerical study on cough droplet dispersion using ANSYS Fluent, analyzing the impact of ceiling fans on evaporation and airborne transmission in enclosed spaces.

Material Behavior Modeling: Developed viscoelastic constitutive models to study the evolution of mechanical properties in thermoset polymers, enabling better performance prediction.

Aerospace & Defense Applications: Designed and validated CFD/thermal solvers for reentry vehicles (for a U.S. client) and landing gear systems (for ISRO, Sarla Aviation).

Passionate about bridging computational mechanics with real-world engineering challenges, I thrive on transforming theoretical models into robust, validated solutions for aerospace and advanced manufacturing.

In my current job i have been involved in :

Study of Reentry vehicles to analyse flow behavior, heat transfer and conjugate heat transfer

Study of landing gears for governmental and private organisations(ISRO, DRDO, Sarla Aviation)
