Pipe flow heat transfer
Webb20 jan. 2024 · Heat transfer occurs when one system comes into contact with another low-temperature system. The energy in the form of heat is transferred from the molecules in the first system to the second system. When the temperature increases, the kinetic energy of the molecules also increases. WebbSpecific fields of interest include multi-phase flows, boiling heat transfer, nano-fluid, optimization, micro-channel and numerical modeling. Currently, I am seeking opportunities that will allow me to promote and develop technologies that would be beneficial in various industrial applications such as air conditioning systems, heat pipes, and domestic …
