Start with your question

Why visitors arrive: You need a quick thermophysical or fluid calculation with traceable correlations.

Your question: What calculators exist, and what assumptions do they use?

You may also be asking

  • How do I size Reynolds or Mach for an experiment?
  • Is there probe uncertainty tooling?
  • Where are the underlying methods documented?

Engineering calculators

Thermophysical utilities I use when setting ECAT boundary conditions, checking Reynolds/Mach similarity for HPT campaigns, and teaching fluid mechanics – documented correlations, SI outputs, part of the engineering knowledge platform.

Air properties calculator

Thermophysics · gas dynamics

Computes thermophysical properties of dry air as a function of local temperature and pressure. Used in practice for ECAT facility operating-point checks on the HPT deterioration programme, nondimensional similarity work in the fluid mechanics curriculum (developed while teaching in Barcelona), and AM heat-exchanger low-order sizing behind the 2024 Engineering Research Express paper.

Tool roadmap

Additional modules are registered in the engineering catalogue as internal workflows are formalised into public tools.

Planned tools are registered in the engineering catalogue and listed honestly here until shipped – see also the instrumentation theme for probe-uncertainty work.

Open to corporate workshops, technical review, R&D roles, consulting, research partnerships, and teaching enquiries – see professional programs.
