Delta T


INR 30,000


A major technical event as a part of the annual technical festival “Pragyan” of NIT Trichy , DELTA T has been a successful event for the past few years, drawing young minds to provide industrial solutions  in designing aspects to temperature change related issues.


Delta T aims to bring out ideas of innovative heat exchanger design and its application in industries. The participants are required to construct a working model of a heat exchanger to effectively transfer heat from a hot source to cold source using a secondary heat transfer fluid without direct contact.


The good old Matka(Mud Pot) has amused children since ages. An amazing technology, ages old. Its time for you to step into the Kelvin-league. Design a new-age day heat exchanger for industrial needs. Amuse us with your design and ThermoD skills.


The mercury is getting high, pull it down. The stakes are high. May the most efficient design win.

Problem Statement :


Design a heat exchanger that can convey heat from a hot liquid(water) to a cold liquid(water) placed .5m apart by the use of the third transfer liquid!

Judging Criteria


  • The elevation in temperature in the cold sink( normal water) given at room temperature initially.
  • The time taken for the entire process.
  • Originality in design.


  • Maximum 3 persons per team.
  • Abstracts must be submitted in the given format. Click here to download the sample abstract
  • Each team will be provided with 1 litre of water at room temperature and 2 litres of water at elevated temperature (60-70oC).
  • The area occupied by the design should be preferably within 1.5m X 1.5m.
  • The water should not be contaminated before, during or after the heat exchange process.
  • There should not be any volume loss in the water provided.
  • Water discharge from the cold sink should be provided in such a way that the water can be collected in a container with insulating walls. The temperature of cold water will be measured from that container.
  • The entire process should be completed in the least time possible (which should not exceed 10 min).
  • No other heating and/or electrical device allowed. Exothermic reactions should NOT be used.
  • Mixing of fluids is not allowed.
  • Unwanted and unnecessary actions or behaviour by participant shall not be tolerated, and will lead to disqualification of the  team.
  • Marks will be deducted for any actions violating the above rules.
  • Judge’s decision is final.
