ANSYS CFX simulation for turbomachinery and flow systems, validated against physical test data rather than left as simulation-only.
What the CFD work covers
Computational fluid dynamics answers questions that are expensive or impossible to answer by testing alone: how a flow behaves inside a turbine runner, where efficiency is being lost to jet interference or pressure imbalance, and how a design change actually affects performance before a prototype gets built.
The background here is turbomachinery specifically — jet dynamics inside hydro turbine runners and pressure distribution across rotating blades — built through a CFD-focused undergraduate thesis and carried into later project and coursework simulation.
What I deliver
3D CFD models in ANSYS CFX, including multiphase setups where more than one fluid phase interacts. Torque and power output calculations validated against physical test rig or prototype data where available. Efficiency-loss diagnosis: identifying specifically where a design is losing performance, not just confirming that it does.
How I work
CFD results are only useful if they're checked against something real. The thesis work behind this was validated against dual-jet Turgo turbine test rig measurements, not left as a simulation-only result — the same validation discipline applies to project work.
Where I've done it
Built a 3D multiphase CFD model in ANSYS CFX for an undergraduate thesis at Kathmandu University, studying jet interaction and bucket filling in a dual-jet Turgo turbine test rig, calculating torque and power output and identifying efficiency losses from jet interference. Supervised by Dr. Sailesh Chitrakar, Department of Mechanical Engineering.
Conducted aerodynamic analysis of a modified Savonius vertical-axis wind turbine using ANSYS CFX to evaluate pressure distribution, then fabricated a 3D-printed prototype to physically validate the rotational mechanism the simulation predicted.
Frequently asked
What CFD software do you use?
ANSYS CFX, for turbomachinery and rotating-flow problems specifically.
Can CFD results be validated against physical testing?
Where a test rig or prototype exists, yes — the underlying thesis work was validated against test rig measurements for torque and power output, not left as simulation-only.
What kind of systems have you modelled?
Hydro turbine runners (Turgo, dual-jet) and a modified Savonius vertical-axis wind turbine. The common thread is rotating machinery and jet or flow interaction, not a specific industry.
Do you also build the physical prototype, or only the simulation?
Both, where the project calls for it — a 3D-printed prototype was fabricated to validate the wind turbine simulation's predicted rotational behaviour.
