Abstract

Heat transfer enhancement due to the helically coiled heat exchanger is a burning topic in the field of research. But so far, there is no experimental or theoretical analysis of a helically coiled heat exchanger considering fluid-to-fluid heat transfer published, hence intending our work on this subject by using Methanol in water solution as a cold fluid. Methanol (also known as methyl alcohol, carbonyl, wood alcohol, wood naphtha or wood spirits) is a chemical compound with chemical formula CH3OH. It is the simplest alcohol and is a light, volatile, colorless, flammable, poisonous liquid with a distinctive odor that is somewhat milder and sweeter than ethanol (ethyl alcohol). At room temperature, it is a polar solvent and is used as antifreeze, solvent, and as a denaturant for ethyl alcohol. The Methanol, when prepared a solution with water, can be used as a coolant in the Heat Exchanger ( Helically Coiled Heat Exchanger in our case) to take advantage of their improved heat transfer properties which would result in enhanced heat transfer in the helical coil heat exchanger. For this purpose, a solution was prepared with varying proportion of Methanol in water. We used four concentrations of 5%, 10%, 15% and 20% of methanol by volume in 5 liters of water. As Water is Polar and Methanol as well. So, when we put methanol in water it gets dissolved and producing intermolecular forces i.e. hydrogen bonding. Various properties such as pH, Electrical Conductivity, Thermal Conductivity, boiling point etc. were tested.
