ThermoPlan


ThermoPlan assess the relative merit of a given measurement considering existing data in SOURCE, including the availability of experimental thermophysical property data, variable ranges studied, associated uncertainties, state of prediction methods, and availability of parameters for deployment of prediction methods.

The web app supports specific property measurements for pure and binary chemical systems, the broader data needs of pure systems, and recommendations for binary mixture measurements that could extend the current UNIFAC prediction model. The algorithmic approach to experiment planning implemented in ThermoPlan is based on technology previously developed for ThermoData Engine.

TRC thermoplan landing page

ThermoPlan is designed to address the increasing need for thermophysical property measurement planning. As the body of internationally available literature data grows larger, ThermoPlan is an increasingly useful resource for maximizing the likely impact of new work.

Features

  • Helps researchers avoid potentially redundant or irrelevant measurements
    • Inputs: compound(s) in system, temperature/pressure range, property measured, projected uncertainty of measurement
    • Outputs: potential value of proposed measurement, similar published measurements (if any)
