Why does a scratched surface act better boiling surface in a Heat Exchanger as compared to a smooth surface?
Why does a scratched surface act better boiling surface in a Heat Exchanger as compared to a smooth surface? The first detailed boiling study was conducted by Nukiyama in 1934 when he plotted the boiling curve showing the relationship between heat and temperature. The curve is known as the Nukiyama boiling curve. Figure 1 shows […]
Shell Side Direct Expansion Evaporation (SX) of Ammonia on a 3-D structured surface Tube Bundle with exit superheat effect
Shell side direct expansion evaporation (SX) of ammonia on a 3-D structured surface tube bundle with exit superheat effect Ammonia is an environmentally safe and low-cost natural refrigerant which has been in use for more than a century. The Kigali amendment phase-out of HFCs has further strengthened the case for ammonia. The limitations of ammonia […]
Why Are Heat Exchangers Needed?
So, why are heat exchangers needed for a wide range of industrial applications? They are used as parts of air conditioning and cooling systems, or of heating systems. And a lot of industrial processes need a specific degree of heat to function. However, a lot of precautions are made to stop these processes from becoming […]
What is an Industrial Heat Exchanger?
Exchangers are possibly one of the most important and widely used pieces of equipment found at various industry sites. Regardless of the industry in question, it will possibly require some type of temperature regulation. That is when exchangers come in. They can be used for heating or cooling, but, in the industrial sector, especially at refineries and […]
What is Renewable Energy?
According to the U.S. Energy Information Administration, “Renewable energy is energy from sources that are naturally replenishing but flow-limited; renewable . . .
