The Immersed Boundary Method has been used to simulate a range of fundamental flows and turbulence. Such studies have demonstrated the method’s promising applicability for engineering analysis. However, to the authors’ knowledge, flows in coupled

Leading edge instrumentation used in compressor and turbine blades for jet-engine test rigs can cause significant obstruction and lead to a marked increase in downstream pressure loss. Typical instrumentation used in such a scenario could be a Kiel-s

RANS models remain an attractive turbulence simulation method which could provide some open jet aerofoil interaction analysis at a fraction of the cost of a high-fidelity LES approach. The present work explores the potential and limitations of RANS i

Serrated jet nozzles are considered to be an efficient and practical passive control approach for jet noise. However, some fundamental mechanisms of serration effects on jet noise are not fully understood, especially in terms of the sound source. In

Theoretical methods are developed to understand the effect of non-uniform grids on Flux Reconstruction (FR) in multi-dimensions. The analysis reveals that the same effect of expanding and contracting grids is seen in two dimensions as in one dimensio

Numerical studies of the flow field and heat transfer in a fully developed ribbed channel have been performed using Large Eddy Simulation (LES). Validation of the LES against measurements shows encouraging agreement. An immersed boundary method (IBM)

A computationally efficient high-order solver is developed to compute the wall distances by solving the relevant partial differential equations, namely: Eikonal, Hamilton-Jacobi (HJ) and Poisson equations. In contrast to the upwind schemes widely use

In this paper, the jet flow from an industrially relevant ultra-high-bypass-ratio (UHBPR) serrated nozzle has been simulated in a flight stream. The methodology to tackle complex geometries and multi-disciplinary physics is demonstrated in detail and
