15W CFL Bulb, Ansys, FinsAbstract
This paper suggest a design of 15W CFL bulb, presents a thermal analysis of circular fin in line and heat
sinks for a high power CFL lighting system. For enhancing the heat transfer rate, circular fin are one of the most
popular choice. The goal of the thermal design of a lighting device is to suggest new design for CFL bulb and to
ensure that the temperature of the bulb stays low, the beautification of the bulb will increase. The addition of the fins,
will increase the heat transfer to the surrounding. A standard k-ε turbulence model consisting of two transport
equations for the turbulent kinetic energy and the turbulent dissipation is used. Results were obtained heat flux for
both with and without fins, heat transfer coefficient and how the temperature varies through the blub surfaces.
