Abstract
Investigating the fluid dynamics and heat transfer aspect of the ultra-high temperature thermal energy storage technology being developed by Dr Adam Robinson in the Institute of Energy Systems at the University of Edinburgh.
I'd be designing and evaluating the use of heat pumps to charge the storage core and to recirculate waste heat to maintain the core temperature. I'd also be investigating if using blade cooling in the heat pump results in acceptably low thermodynamic losses, and more generally investigating the aerodynamic considerations and heat transfer in the heat exchangers. I'd be designing a valve to switch between using hot combustion products in the power generating gas turbine, and nitrogen heated from the storage core. I'd also be investigating the reheat system used in the power generating gas turbine.
The work would involve writing computer code to take account of the additional effects of heat transfer and structural considerations in computational fluid dynamic simulations. Mathematical models of the various system components would be developed and compared with experimental data obtained from a scaled down test rig of the thermal energy store. It would also be desirable to develop a numerical model of the complete system in order to perform transient analyses.

Description | I have managed to produce a numerical model (i.e. a computer program) that is able to predict the performance of monolith (honeycomb type) heat exchangers. This model can be used in the design and optimisation of these heat exchangers. These heat exchangers have applications in thermal energy storage systems and beyond. |
Exploitation Route | Anybody who needs to design or optimise monolith heat exchangers could put this tool I have created to use. Monolith heat exchangers are used in transport, energy storage, aerospace and manufacturing, to name but a few areas. |
Sectors | Aerospace Defence and Marine Energy Manufacturing including Industrial Biotechology Transport |
Description | Improved understanding of the heat transfer within monolith heat exchangers. This has uses not just in thermal energy storage systems, but also in aerospace, transport and manufacturing. |

Title | Numerical model for heat transfer and pressure loss in monolith heat exchangers |
Description | Written in C++, this piece of software generates a monolith heat exchanger geometry, meshes it, and then models the heat transfer within the solid & fluid, and the pressure loss experienced by the fluid. External boundary conditions can be supplied as inputs. |
Type Of Technology | Physical Model/Kit |
Year Produced | 2019 |
Impact | It will allow monolith heat exchanger designs to be optimised automatically. |
