An engineering studio for thermodynamic systems
vapor.estate is a browser-based thermodynamic simulation studio for thermal-fluids engineers. You connect components — pumps, turbines, compressors, heat exchangers — on a visual node graph, and an equation-oriented solver resolves every thermodynamic state point in the system. It brings power-cycle design and fluid-property lookups into one fast, modern workspace.
The name is a play on thermodynamic state — the .estate ending nods to the state points that define a fluid. It has nothing to do with real estate; vapor.estate is engineering software.
Everything you need to model thermal systems
From a single Rankine loop to a multi-stage ORC, vapor.estate turns thermodynamic design into a visual, solvable model.
Visual cycle design
Drag components onto a canvas and wire their ports together. Your thermodynamic cycle is a graph you can read at a glance.
Equation-oriented solver
Streams become variables and components become equations. A Newton solver finds the consistent solution across the whole network.
Power cycles
Model Rankine and Organic Rankine Cycles (ORC), single- or two-stage, with pumps, turbines and heat exchangers.
Fluid properties
Accurate thermophysical properties for a curated catalogue of working fluids, backed by trusted equations of state.
Runs in the browser
No installation, no licences to manage. Open a tab and start designing thermodynamic systems anywhere.
From sketch to solved state in three steps
Build the cycle
Place components on the canvas and connect their streams to describe your thermodynamic system.
Set the conditions
Specify pressures, temperatures, efficiencies and the working fluid. The model tracks the degrees of freedom for you.
Solve & inspect
The solver computes every state point. Read enthalpies, work, heat duties and efficiency across the cycle.
Built for people who think in state points
Frequently asked questions
What is vapor.estate?
vapor.estate is a browser-based thermodynamic simulation studio for thermal-fluids engineers. You build power cycles such as Rankine and ORC on a visual canvas, and an equation-oriented solver computes every thermodynamic state point.
Is vapor.estate a real estate website?
No. Despite the .estate domain, vapor.estate has nothing to do with real estate or property. The name is a play on thermodynamic state — the .estate ending nods to the state points that define a fluid. vapor.estate is engineering software for thermodynamics and cycle design.
Which thermodynamic cycles can I model?
vapor.estate focuses on power and thermal cycles, including the Rankine cycle and the Organic Rankine Cycle (ORC), in single- and two-stage configurations, plus general thermal-fluids networks built from pumps, turbines, compressors and heat exchangers.
