Stability and Thermal Conductivity Characteristic of Carbon Nanotube Based Nanofluids

Heat transfer fluids such as water, ethylene glycol and engine oil are commonly used in heat exchanger applications. However these fluids posses low thermal conductivity. The technology advancement in nanotechnology has enabled the nano size particles to be included in a base fluid. This new generat...
