Arun

Dr Arun Arjunan joined the Faculty of Science and Engineering at the University of Wolverhampton in August 2014 as Lecturer and Course Leader in Mechanical Engineering. He attained his PhD in Mechanical Engineering working on a collaborative research project between the Hadley Group PLC and University of Wolverhampton to optimise the thermal and vibro-acoustic behaviour of stud based double-leaf walls.

                                                    

Dr Arjunan received the FHEA status being recognised as a Fellow of the Higher Education academy in 2014 by exhibiting key competence for ‘Academic as a Teacher’, ‘Academic as a Designer’ and ‘Academic as a Researcher’. His first degree is in Mechanical Engineering and completed his PgC Academic Practice in Higher Education (PgCer-HE) in accreditation with the UK Higher Education Academy (HEA).

 

Areas of research specialism and consultancy are in the fields of structural mechanics and finite element analysis. His research on the numerical simulation of the vibro-acoustic behaviour of stud based double-leaf walls has been widely cited as a significant contribution by specialist in the field. Dr Arjunan also serves as a reviewer for the Elsevier Journal of Building and Environment and Springer Journal of Mechanical Science and Technology

  • Structural mechanics and stress analysis
  • Vibro-acoustic behaviour of structures
  • Finite Element Analysis (FEA)

Research and Consultancy are in the broad field of structural mechanics, numerical modelling of vibro-acoustics and application of the Finite Element Method to study structural and fluid-structure interaction problems. Expertise includes the utilisation of finite element method to simulate the vibro-acoustic and heat transfer behaviour of stud based double-leaf walls.

 

Current research projects

 1.      Numerical Simulation of Airborne Sound Pressure Level in a Manufacturing Environment

The European Agency for Health and Safety at Work estimates that over 2 million people in the UK are exposed to loud noise at work on a regular basis. From that, 1.1 million workers in a manufacturing environment are exposed to noise levels above 85 dB, which causes significant risk to health and wellbeing. Noise issues in manufacturing environments are widely discussed from a legal and health standpoint. However, there is no comprehensive method to simulate such phenomena to deliver possible improvements. The prediction of airborne noise level in a manufacturing environment is a challenging problem due to the Fluid-Structure Interaction (FSI) between structural and fluid systems along with multiple noise sources and the broad frequency range. The current research work provides an early investigation into the possibilities of using the Finite Element Method (FEM) to simulate and analyse the airborne noise levels within a manufacturing environment undergoing FSI.  The FE model is expected to visualise the spatial SPL, thus establishing a new viewpoint for the diagnosis and reduction of noise levels at a factory planning stage.

 2.      Vibro-acoustic Simulation of Roll-formed Steel Studs

 

Partition walls using roll-formed steel sections are widely used in modern construction due to their popularity over traditional masonry partitions to reduce construction cost and time. Accordingly, stud manufacturers are making great efforts to improve the vibro-acoustic behaviour of steel studs by testing various stud designs. However, these laboratory tests are often time consuming, expensive and require specialist equipment and prototypes. In order to deliver design improvements in a cost effective manner, efficient simulation models that can predict the sound reduction index of stud walls are needed at the design stage. Consequently, this work provides the development of an FE model that can predict the sound reduction index (R) of stud walls at one-third-octave band. This research is carried out in collaboration with Hadley Group PLC to create acoustically efficient structural sections.

Human Powered Flight Project

 

DrArjunan leads the Human Powered Flight (HPF) project at the University of Wolverhampton. The purpose of the HPF project is to design, develop and fly a Human Powered Aircraft (HPA) in line with the Royal Aeronautical Society (RAeS) HPA guidelines, and engage in various HPF competitions as the ones organised by RAeS. This is a student managed design and build project linking theory with practice in addition to providing unique analysis skills. For engineering students the HPF project offers the most exciting challenge right from material selection to producing ultralight structures, engineering design, project planning, team working and budgeting. Finally, creativity and innovation is the corner stone alongside practical building skills to ensure a successful flight.
