+  abstract    = {This work presents an aerothermal investigation of a novel turbomachine used for light olefin production. The
+turbomachine – the Roto-Dynamic Reactor (RDR) – replaces the radiant section of a conventional steam cracking
+plant. The design objectives are to efficiently transfer shaft work (provided by an electric motor) to the working
+fluid whilst minimising the residence time, hydrocarbon partial pressure, coking and secondary reactions, and
+increasing the olefin yield and process temperature. The novel reactor is comprised of a 1.5 stage turbomachine
+with the outlet of one stage connected to the inlet of the next through a toroidal-shaped vaneless diffuser space.
+This yields a regenerative design. The concept is investigated using the in-house CFD code TBLOCK using a
+combination of Reynolds-averaged Navier-Stokes (RANS) and large eddy simulation (LES) strategies. Numerical
+investigations show a steady rise in temperature across the reactor with a higher outlet temperature (T = 1350 K)
+than typical conventional pyrolytic reactors. The pilot design shows a low residence time of 53 ms for an average
+particle and significantly higher viscous shear stresses than conventional furnaces. These two factors solidify
+the economic feasibility of the concept. This work validates the regenerative nature of the design, with the flow
+progressing as nearly independent streamtubes. Numerical results confirm the design requirement of a temporally
+and circumferentially uniform inlet field at the inlet of each regenerative pass of the reactor. Secondary and
+tip leakage flow mechanisms are explored to determine the impact on work added to the working fluid. The
+high-turning impulsive blading results in very large losses in work coefficient. Shock systems are probed in detail
+to understand the process of energy transformation into internal energy, in addition to the shockwave/boundary
+layer interaction that promotes strong mixing. This internal mixing within a regenerative pass is required to enable
+a regenerative design and prevent secondary reactions. The current design exhibits sufficient internal mixing to
+decrease the static pressure, but also to drive chemical reaction and crack long-chain hydrocarbons into shorter
+molecular structures. This work introduces guidewalls to mitigate lateral mixing between adjacent regenerative
+passes and improve the guiding of the flow in the vaneless diffuser space.},
