Notes Abstract: The ever-continuing trend in miniaturization and ever-growing power density requirement of portable electronics has necessitated the search for alternate sources of compact power with high energy content. To this end, new technologies such as microscale heat engines, micro fuel cells, micro-thermo photovoltaic and micro-thermoelectric generation are being developed as possible alternatives to traditional battery technologies. Among these, thermoelectric generators boast many key advantages such as robustness, reliability and long-life. Thermoelectrics devices enable the direct conversion of heat energy into electrical energy.
Shell and tube heat exchangers are the most popular and widely used heat transfer equipment in process industry. The first step in the engineering design of a new heat exchanger is to finalize the process parameters such as -. Based on this information, mechanical engineers then prepare a mechanical datasheet that can be used by the heat exchanger manufacturer for final fabrication. Process design of a shell and tube heat exchanger is an open ended problem. There are more parameters or variables than there are constraints.
