A set of all blades were initially designed and numerically simulated. However the blade has not yet manufactured and tested in labs. We are looking for investor who can envest on further study, manufacturing and testing. as we are sure about numerical simulation because we have established for other fans and expecting the same as we have developed the methodologies.

After manufacturing and testing of the HVLS fan, The air delivery, torque and power results obtained from numerical simulation must highly agree with the experimental data with error lower than 3%.

The analysis of air flows over the ceiling fan blade has been performed computationally and all the data has been verified through the experimental results of existing HVLS fan. Based on the previous study by the other researchers also has been computationally testes and verified. Here, in this research we have redesign the HVLS fan blade profile for extracting maximum energy from the still air and converting it into kinetic energy for the thermal comforts. The dynamic behaviour analysis of air flows over the HVLS fan blade has been performed computationally.
