INVESTIGATION OF ELLIPTICAL AND CONICAL FLOWER-SHAPED INTERNAL RIBS TO DETERMINE TEMPERATURE DISTRIBUTION AND NUSSELT NUMBER

A fin is a tiny appendage or component that is connected to a larger body or structure. Fins are often used as foils to provide lift or push, or to guide or stabilise motion when travelling in water, air, or other fluids. Fins are surfaces that protrude from an item in order to improve the rate of heat transfer to or from the environment through increased convection. The quantity of heat transferred by an item is determined by its conduction, convection, or radiation. Heat transfer is increased by increasing the temperature difference between the item and the environment, the convective heat transfer coefficient, or the surface area of the object. Internal shaped fins of various forms have gotten a lot of attention over the last few decades because of their potential advantages over traditional overhead forced heat transfer systems. The intake air velocity, temperature distribution throughout the system, and mass flow rate all have a significant impact on the extended surface heat exchangers. In this work, we are analysing the temperature distribution, nusselt number, and friction factor of their internal fin configuration, which was used for simulation, and it was discovered that sample – 2 with tapered fin enhances better nusselt no. as well as temperature distribution is maximum compared to other fin configurations in the mass flow rate of 0.0395 kg /s.
