This thesis develops a contingency-based model for competitive advantage, tested over time on a sample of rapidly growing small-to-medium enterprises. Incorporating two independent studies, the project addresses interactions between specific elements of strategic orientation, strategic behaviour, firm performance, while examining the moderating role of environmental turbulence.

The current research is undertaken by performing Computational Fluid Dynamics (CFD) simulations for a 2D aerofoil fitted with a shock control bump at a transonic flow condition. Reynolds-Averaged Navier-Stokes equation coupled with turbulence models is adopted to solve the flowfield. The bump has a conventional geometric feature which consists of a ramp, a crest and a tail, and it has eight variants for which the designed parameters are reasonably specified according to the compressible aerodynamics theory.

The goal of this study is to demonstrate and quantify the impact that the uncertainty in thermophysical properties has on key metrics of thermal hydraulic importance for MSRs, in particular on the heat transfer coefficient. In order to achieve this, computational fluid dynamics (CFD) simulations using the RANS k-ω SST model were compared to published experiment data on molten salt.

This paper proposes a hydrodynamic/sediment model for simulating bedload sediment through a river section. Firstly, flow characteristics such as depth-averaged velocity were obtained by solving the governing equation, which is derived from the Reynolds equations and allows for taking into account the gravity, bed shear stress, turbulent diffusion force and secondary flow in calculations.
