Flow disruption can be achieved through passive surface modifications, such as, shape of channel, dimple surfaces, ribs, cavities, groove structures, porous medium, etc.Combined effects of these geometrical configurations in heat transfer augmentation are also reported in the literature.The bodies (called models) are usually scaled down but geometrically similar versions of bodies of interest like an airplane or an automobile.
Each model from the three heat exchangers was analysed and parameters like temperature, pressure and velocity were compared. INTRODUCTION A wind tunnel is an aerodynamic test facility.
It is mostly used to study flow patterns around bodies and measure aerodynamic forces on them.
Subjects covered in Heat Transfer Research encompass the entire field of heat transfer and relevant areas of fluid dynamics, including conduction, convection and radiation, phase change phenomena including boiling and solidification, heat exchanger design and testing, heat transfer in nuclear reactors, mass transfer, geothermal heat recovery, multi-scale heat transfer, heat and mass transfer in alternative energy systems, and thermophysical properties of materials.

A good amount of heat transfer augmentation techniques have been reported on flow disruption through microchannel.
These techniques promote free stream separation at the leading edge which results in boundary layer development and enhanced mixing leading to increased heat transfer.
Microchannels, with their large heat transfer surface to volume ratio and their small volumes, have shown a good thermal performance.
Microchannels have been proven to be a high performance cooling technique which is able to dissipate heat flux effectively from localized hot spots over small surface area.
