Heat transfer experiments on thin-film flows

Meer, Belgium — The Department of Chemical Engineering at Imperial College London (UK) has elected to use a FLIR Systems X6540sc thermal imaging camera to conduct innovative heat transfer experiments on thin-film flows.

Studying heat transfer in thin-film flows is the key to enable the accurate prediction of complex hydrodynamic processes, crucial for the design of many engineering systems that rely on these flows.

Research within the Clean Energy Processes group at the Chemical Engineering Department of Imperial College London is aimed at the development and employment of new imaging techniques for conducting simultaneous spatio-temporal measurements of thickness, velocity, temperature and heat flux in thin-film flows.

SSE Sensitivities (Size-of-Source)

In Most IR Thermometers or Radiation Thermometers

SSE Poster image

Online — A recent online copy of a significant technical poster, Size-of-Source Effect Sensitivities In Filter Radiometers, (Authors: M. R. Dury, T. C. Arneil, G. Machin and M. Goodman), on the National Physical Laboratory (NPL) website  is now freely available as a PDF (1.05MB) download online on the NPL web site.

The introduction to the article begins:

“When performing high accuracy radiation thermometry, the size-of-source effect (SSE) of a filter radiometer* can provide a significant contribution to the uncertainties** associated with the measurements.” Continue reading

Online — Cleaning your infrared camera’s lens is a rather simple procedure if you understand the seriousness of what you are doing as well as the consequences of doing it incorrectly.

First, know that the lens of an IR camera can be very expensive. Continue reading

IR Window Materials

A useful guide to a wide array of Infrared Materials used for windows and, for some, lenses.

This guide, on the Lawrence Berkeley Laboratory website, while very useful is designed for those most familiar with infrared properties described in terms most often used by infrared spectroscopists, often chemists, and stated in terms of wavenumbers in cm-1 rather than microns of micrometers, a term more familiar to engineers and infrared thermographers.

An explanation of how to do the actual conversion may be easily found online by googling the actual terms “converting wavenumbers to microns”. One of the current responses is: “How to convert cm-1 to microns or nanometers at

It is actually very straightforward because: Wavelength in µm = 10,000/cm-1
