Draw the system.
Solve the physics.
Cycles, flow networks, and everything between — constrained like an engineer thinks, solved with real-fluid properties, then swept across the whole design space. All on your own machine.
Constrain. Solve. Read.
Specify what you know
Every stream carries three unknowns — P h ṁ.
Components contribute their governing equations: isentropic efficiency,
Darcy–Weisbach friction, effectiveness, elevation head ρgΔz.
One simultaneous system
A trust-region least-squares solve over the whole network at once — no marching order, no tearing, no guessing which component goes first.
Honest diagnostics
Fully constrained, or told exactly why not: underconstrained with
the missing degrees of freedom counted, overconstrained when your
specifications conflict. Never a silent wrong answer.
Don't solve one design.
Explore a thousand.
Pick any input — turbine inlet temperature, condenser pressure, mass flow — and sweep it across a range. ThermoFluid Studio re-solves the entire system at every point and plots the result, so you find the optimum instead of guessing at it. This is the difference between a calculator and a design tool.
- Sweep any component setting or boundary condition
- Watch efficiency, COP, net work, or any state respond
- Export the entire study to CSV in one click
- Every point is a full, verified solve — never an interpolation
Every example is a proof.
Fifteen systems ship in the app — every state in every one re-derived by hand from CoolProp, independently of the solver, and published with the full algebra.
Small tool. Real solver.
Design exploration
Sweep any parameter across a range and re-solve the whole system at every point. Plot efficiency, COP, or net work against your variable and find the optimum — then export the study to CSV.
19 component models
Turbines, pumps, compressors, boilers, condensers, recuperators, throttles, nozzles, mixers, splitters, pipes, bends — with the actual equations documented.
Real fluids, not tables
137 fluids through CoolProp — steam, refrigerants, cryogens, CO₂ through the critical point. Quality, superheat, and subcooling are ordinary specifications.
Multi-loop systems
Independent fluid loops — a steam cycle and a refrigerant loop in one project, each with its own fluid and mass flow, summarized together.
Diagrams that trace processes
T–s, P–h, P–v, and Mollier diagrams with real saturation domes — boiling plateaus ride the dome, throttles follow their isenthalps. No chords between dots.
Hydraulics included
Darcy–Weisbach friction with laminar and Swamee–Jain regimes, Crane-method bends, minor losses, heat loss, and signed elevation head ρgΔz.
Private by design
Projects are local .tfluid files (inspectable JSON). Nothing you model is uploaded, stored, or processed on any server.
One product. One price.
