The convection heat transfers on a surface exposed to the fluid may be enhanced by attaching to the surface, known as the fins. To keep the system stable, heat transmission via solids, boundaries, or walls must be continuously dissipated to the environment or surroundings. A large quantity of heat must be dissipated from a small space in many engineering applications. A fin can boost the surface area’s effectiveness; hence, maximize convectional heat. Two shapes of straight aluminum fins have been used, cylindrical and star shape. The result shows that the star fins are appealing due to the same diameter and length; it has a lot more heat transfer than a cylindrical fin. In electronic devices, cylindrical and star fins are provided on the surface of the processor device. The result is done by SolidWorks simulation with 300 ºC on the surface as well as cylindrical and star fin. Input parameters like thermal conductivity, heat transfer coefficient, as well as fin’s density and dimensions are measured. The temperature distribution, heat flow, as well as heat flux all resembles output parameters.

The extant research design LPG give a good temperature distribution for a specific burner design of low consumption burners and relays to a method for bending the glass sheets, in which method the swirl burner LPG is used in a small furnace. Using LPG fuel gives more stability in the combustion process, the LPG is a gaseous fuel that helps to have easy control of the combustion rate and the temperature behavior inside the combustion zone by increasing and decreasing the mixing ratio with air. The heat flux from the flame moves in the front direction due to the momentum of the fuel mixture and the design of the burner rim, which keep the flow adhesive, such behavior leads to creating different temperature zone since the combustion process is a continuous process. The main result is that clean or low emission combustion of LPG fuel will increase the gained temperature and give a good temperature distribution for a specific burner design of low consumption burners and the clean combustion will reduce the unwanted deformation of soot on melting glass surface. Generally, high energy cost and the environmental pollution are the major issues in the glass industries which must be reduced through reduce the fuel consumption of the glass furnaces. For these reasons, this type of furnace can be used in other applications, not only in melting glass.
