According to some estimates, heat transfer coefficients with the twisted-tube design are 40% higher than those found in a conventional shell-and-tube heat exchanger with a similar pressure reduction.
with being the overall heat transfer coefficient, the heat transfer area, and is the log-mean temperature difference. Equation (13)(13) is used when simple counter or co-current flows exist. If the flow pattern is more complex (such as the case with most shell and tube heat exchangers), then a correction factor ( ) term is used and the
SHELL AND TUBE HEAT EXCHANGER DESIGN "PART A" STEAM SHELL AND TUBE HEAT EXCHANGERS The shell and tube heat exchanger (STHE) is the workhorse in the steam world, and it is used in many process steam applications. The design is very flexible to meet the strenuous requirements found in steam and condensate systems. Industrial heat exchanger types include the most common double pipe heat exchangers, shell and tube heat exchangers, as well as spiral, flat plate, and fin tube heat exchangers. The design of heat exchangers makes use of convection heat transfer coefficients and a calculated log mean temperature difference, along with information about the ... Here is a set of steps for the process. Design of a heat exchanger is an iterative (trial & error) process: Calculate the required heat transfer rate, Q, in Btu/hr from specified information about fluid flow rates and temperatures. Make an initial estimate of the overall heat transfer coefficient, U, based on the fluids involved. Academia.edu is a platform for academics to share research papers.
