How to Apply

How to Participate


E-mail the drawing file and entry form to by no later than March 1, where there is only a single deadline this year. Note that the drawing and entry files must be named as CELERE_2018____ where the drawing is a dwg file and the entry file is in a pdf or doc format.

Key Documents

The following documents should be downloaded as you will need them for background information, as you work on this design challenge and/or to submit your entry as discussed in the Preparation and Submission section below.

CELERE Overview
CELERE 2018 Handbook
CELERE 2018 Tutorial
CELERE 2018 Entry Form
CELERE 2018 TESTCELL TEMPLATE  (you will need the DraftSight software to open this file)
DraftSight Software

Preparation and Submission

  • Explore the CELERE website at
  • If you are a Facebook user, ‘like’ the CELERE page at
  • Read the this year’s CELERE handbook.
  • Learn about capillary action, e.g., through:
  • Review the past experiments through and the appendix of the CELERE handbook.
  • Download this year’s CELERE tutorial.
  • Download this year’s drawing template.. The test cell has been redesigned and use of past templates is unacceptable.
  • Download the Draftsight CAD software and go through the CELERE tutorial. You may use other CAD software that works with ‘dwg’ files, but the tutorial is based on the free Draftsight software.
  • Review the CELERE design requirements and common mistakes in the CELERE Handbook.
  • Develop your research question.
  • Design your test cell so that (1) the results will answer your research question and (2) it is different from the past CELERE experiments shown in the appendix.
  • Download the CELERE entry form and fill it out.
  • Verify that all design requirements are fully met or risk rejection!
  • E-mail the drawing file and entry form to to by no later than March 1, where there is only a single deadline this year.

Testing and Analysis

  • If requested, revise your test cell drawing. Revisions are sometimes requested when entries are tentatively selected even though design requirements are not met.
  • Selected experiments are normally conducted during the month of their submission deadline.
  • When the results are ready, we will provide you with a sight to download your results.  Note that the video files are not standard, but can be viewed using VLC Media Player, which can be freely downloaded from
  • Analyze the results by comparing the capillary motion in your test cell’s channels. You can determine the position of the oil in each channel as a function of time (e.g., knowing that high-speed video includes 60 frames per second). The position can be determined in pixels, e.g., using Microsoft Paint, which shows the position of the crosshairs in pixels, and then converted later into millimeters.
  • From the position data, average speeds can easily be determined.
  • Prepare a short final report about what you learned, and e-mail the report to (where the submission might be done by your teacher/advisor). The report should include discussion of what was good about the CELERE Design Challenge and what needs improvement.

Key Changes from 2017

  • The maximum number of entries from a single school or organization has been reduced to 7.
  • The tentative plan is to reject entries which violate the design requirements, whereas the 2013-2017 approach was to request the teams to revise their CAD drawings to correct shortcomings.
  • It is anticipated that the CELERE design challenge will not be offered in the future, i.e., after 2018.
  • High-performing participants will be invited to present their results in a student poster session at a technical conference as described in CELERE 2018 Handbook, etc.
  • The freely-downloadable DraftSight software upon which the tutorial is based has been and continues to be updated.
  • The drawing template has been updated.  Please use the 2018 drawing template which can be downloaded from this page.  The other supporting documents – such as this handbook, the tutorial, and entry form – have also been updated.
