A bench top accessory designed to allow students to experimentally investigate both free (natural) convection and forced convection. A heated flat plate with surface thermocouple may be directly compared with a similar pinned plate and finned plate also fitted with a surface thermocouple. Three plates with integral heaters and temperature sensors are also supplied that are designed to fit in the central aperture in the wind tunnel. The accessory includes a small, variable velocity wind tunnel with a digital velocity meter and a central aperture. This allows investigation of the temperature distribution along the extended surfaces. In addition to expanding understanding of the heat transfer enhancement from extended surfaces, the pinned and finned plates each have three thermocouples arranged at intervals along a fin and a pin.

Ltekonline are the manufacturers of Free and Forced Convection From Flat, Pinned and Finned Plates used to demonstrate engineering principles in Engineering Colleges, Engineering Schools and Heat Transfer Lab Equipments for Engineering Teaching Lab in Universities
