ABOUT
This is a self-funded PhD opportunity within the field of Computational Fluid Dynamics (CFD) which aims to further develop Cranfield’s digital wind tunnel (DWT). The DWT removes the need to specify a detailed simulation setup which is replaced by an abstraction layer. This layer, in turn, is driven by flow scenarios / best practices. Given a particular application (flow scenario), a set of freestream conditions and a CAD model (the same parameters required for wind tunnel testing), the DWT is able to automate the entire simulation from meshing, solving to post-processing, using any CFD solver. The applicant will develop a demonstrator as part of this project.Computational Fluid Dynamics (CFD) software these days have matured to a point where using them requires an experienced CFD engineer or researcher to operate them. They offer a variety of interfaces (Graphical user interfaces or console-based) and have very specific and customised workflows, which means that users using a particular software may not be able to change to another CFD solver without a substantial training time investment. The Digital Wind Tunnel (DWT) developed at Cranfield University removes the detailed knowledge required for each solver by providing an abstraction layer from which detailed solver setups can be produced. The abstraction layer will be driven by so called flow scenarios, which are a set of instructions that will set up the simulation based on best practices. For example, the “external steady aerodynamics” flow scenario may have a parameter for modelling requirements where the user can specify the required resolution (high/low fidelity). This will then be translated into an appropriate turbulence model setup using a RANS model that works best for external aerodynamic applications (e.g. k-w SST or Spalart-Allmaras as well as a suitable near-wall treatment as necessary). The user then selects the CFDS solver which should be used and the DWT will produce the required simulation setup and performs the meshing, solving and post-processing all at once. A demonstrator for the DWT has been developed at Cranfield University which showcases the entire process from meshing, solving and post-processing using OpenFOAM. This project will mainly focus on generating the abstraction layer, which will need to be general enough so that many different CFD solvers can be included while being specific enough to be able to provide simulation setups reliably. On top of the abstraction layer, the structure / layout of flow scenarios will need to be developed and standardised as well. Both of these concepts then need to be integrated into a single application. It is envisaged to use Python for this step, which will take a set of user inputs (inlet velocity, ambient temperature, pressure and density + CAD geometry) and then produce the required simulation files.
Entry requirements
Applicants should have a first or second class UK honours degree or equivalent in a related discipline. This project would suit someone with a background in mechanical, aeronautical, automotive, civil / industrial and/or software engineering (or similar). The ideal candidate will be proficient with at least one CFD solver and one programming language (ideally object-orientated). Knowledge on software architectures (microservices), containers (docker, kubernetes), cloud-computing (Azure, Google cloud platform, AWS) and web-development are considered beneficial but not essential

accommodation
The School of Water, Energy and Environment, the School of Aerospace, Transport and Manufacturing, and the School of Management are located on the Cranfield Campus, as well as many industrial-scale facilities for research.
There are many facilities on Cranfield Campus, including: student accommodation options, two hotels with full accommodation and conference and banqueting facilities, sports and recreation facilities, and a private airport. Cranfield Campus sports facilities include several tennis courts sports pitches, playing fields, an aerobics stadium, and a fitness center.
Students admitted to a full-time course can apply for on-campus accommodation. They will also be able to find private housing off campus in nearby areas. Cranfield Campus has 1,466 single rooms, 75 studio apartments for couples, and 97 family homes including two-bedroom, three-bedroom, and four-bedroom houses. All dormitories have Wi-Fi internet connection. All students will benefit from Endsleigh insurance, which covers the risks that may occur while living in student accommodation.
Cranfield University provides many opportunities for students to participate in a various range of societies and clubs, such as the Musicians Society, Astronomical Society, and Basketball Club. The Cranfield Student Association is managed by a team of selected students. It is also supported by a small team of staff. Its purpose is to promote student welfare and to organize cultural, social, and sporting activities.
Cranfield has a wealthy collection of library resources and services to support students’ academic work. This collection has nearly 200 academic and leading commercial databases which provide access to in-depth application topics and current information related to the subject under study. It also has more than 22,000 e-journals, as well as core collections of reports, magazines, books, and a range of current awareness services.
Cranfield provides support, services and systems, whether industry-leading software and high-performance computing capabilities or network access. It offers a high-speed, wireless network to provide students with the opportunity to access a wealth of online services. Cranfield IT services are available 24 hours a day, 7 days a week, on and off campus, and gives students access anytime, anywhere.
After Graduation
Students will benefit from Cranfield Career Development Services, which have a variety of aspects and functions, from providing 1: 1 coaching to connecting with employers. Students will have access to some key resources before entering the university to prepare their resume for the recruitment season. Upon arrival they will be able to join workshops to create their own professional profile and start applying for vacancies. During the year, Cranfield organizes events, careers fairs, and client presentations to present job opportunities and networking, where students attend interviews and negotiate proposals.
From 1 July 2021, the British Government has launched a new route for international graduates to increase their employment opportunities in the UK. This route welcomes all international students who have successfully completed their course at Cranfield. This visa allows MSc graduates for two years and doctoral graduates for three years to work or search in any position or job they wish and it can be converted to a skilled work visa after finding a job in
