Developing the Product - Room Heater - using DFA for Evaluation of the Design Phase while Enhancing the Heating Efficiency for its Functional Attribute

The traditional room heater uses a heating element to heat with a fan or blower to spread the heat in the surrounding space within the room. This research work looks into the possibility of enhancement in the heat for the air passing over the heating elements of the room-heating device. The constraint of maintaining the power input as the existing and keeping the pressure drop in reasonable range. The higher amount of the heat transferred to the air flowing over the heating element shall help in realizing higher efficiency of the product and improve the perception over the utility device. The methodology applied for the work entails developing baffles across the filament to aid higher rate of heat transfer and minimize pressure drop. This variant shall be analyzed using Analytical/ Numerical techniques. The work shall evaluate the problems while also deploying suitable Mathematical model or any other Statistical tool for data analysis. The variant has been developed for physical experimentation in an effort to validate the findings during the analytical phase of work. Tools like DFA for improving the configuration of the room-heater shall be further dealt within the scope of 'Product Design and Development'.
