CFD simulation of Heat Transfer and Flow through Additively Manufactured Internal Structures for Heat Exchangers
Background:
Heat exchangers are among the most widely used devices in the process engineering industry. Until now, the design of heat exchangers has been determined and limited by the available semi-finished products, such as tubes or embossed plates, and conventional manufacturing processes.
Additive manufacturing now offers the possibility of completely new equipment concepts and optimizations, including improved flow control and, in particular, internal structures. Due to the complex geometries of these structures, only very limited correlations are available for determining heat transfer and pressure loss. This, in turn, represents a significant obstacle to maximum efficiency in heat exchangers.
Task:
For this reason, CFD simulations of additively manufacturable internal structures are to be carried out in this work.
The task includes determining the appropriate mesh fineness and validating it against measurement data during the simulation setup. Following the setup of the simulation, correlations for heat transfer and pressure loss are to be derived. If possible within the time frame, a further, optimized structure can also be created and simulated.
Start: As of now
