Computational Blast Modelling with ProSAir - Introduction

Computational Blast Modelling with ProSAir - Introduction

Introduction To Computational
  • Please enquire for course dates
  • Duration: 1 day
  • Location: Shrivenham campus

This one day course introduces the basics of computational modelling of high explosive blast waves and their loading on structures using Cranfield University’s commercial software package ProSAir. Computational fluid dynamics (CFD) modelling, using a low memory and highly optimised package such as ProSAir, allows for rapid and cost-effective assessment of geometrically complex blast scenarios compared to experiment.



  • Course objectives

    Delegates will gain:

    • The mathematical and numerical modelling knowledge required to assess the suitability of ProSAir for a particular blast loading application
    • Training in setting up and running ProSAir.
  • Course topics

    Mathematical Modelling and Discretisation

    • Sources of error – modelling error, discretisation error, rounding error
    • ProSAir’s mathematical model and associated modelling errors
    • Finite volume discretisation – approximate Riemann solvers, TVD schemes, boundary conditions
    • Solution process overview

    Charge Modelling and Using Symmetry

    • Bursting sphere approximation for spherical charges
    • Exploiting spherical symmetry
    • Hemispherical ground-burst
    • Exploiting cylindrical symmetry
    • Height of blast simulations
    • Solution transfer process
    • ProSAir Practical – performing spherical air-burst and height-of-blast simulations, post-processing, cylindrical containment.

    3D Simulations and Geometric Features

    • Adding geometric features - constructive solid geometry
    • ProSAir Practical – performing 3D simulations

    Glazing Damage and Practical Issues

    • Glazing damage – iso-damage curves
    • Batch processing
    • Post-processing
    • Error estimation

    User Workshop

    • Users have the opportunity to apply ProSAir to a problem of their own, or follow one of the documented examples, assisted by course staff

    Future Developments

    • Developments in progress – propellant burning, multiple charges, shaped charges
    • Proposed developments – mesh adaptation, casing effects
    • Delegate requirements – a chance to influence development of ProSAir  
  • Timetable

    Once per year and by request.

  • Who should attend

    Engineers working in blast protection or explosive hazard assessment/design who must evaluate the loads on structures in the vicinity of a high explosive detonation.

    Entry requirements: Degree in an engineering discipline; some experience of design of structures to resist blast loading is desirable.

  • Speakers

  • Course delivery

    This 1 day course is delivered via a mixture of:
    • short lectures to deliver key theory and best practice
    • computer practicals to train delegates in the use of ProSAir and underpin the theory.
    All delegates receive a course folder containing all material presented in the course, a 60 day trial licence for ProSAir and 60 days access to online material used in the practicals.
  • Course fee

    £350

    Shrivenham campus

    Cranfield Defence and Security (CDS) is a School of Cranfield University that offers unique educational opportunities to the Defence and Security sectors of both public and private sector organisations.

    Based at the UK Defence Academy at Shrivenham in Oxfordshire, we are the Academic Provider to the UK Ministry of Defence for all postgraduate education at the Defence Academy College of Management and Technology and training in engineering, science, acquisition, management and leadership. Integrating the resources of the MoD and Cranfield University to deliver a wide range of postgraduate courses in science, engineering and management related to the defence sector, most of which are open to both military and non-military students. Cranfield academics in conjunction with serving officers from the Armed Forces combine to provide dynamic, applied and practice courses. Facilities on the campus include an outdoor heated swimming pool, golf course and a wide variety of other sporting facilities.

    The Shrivenham campus is well positioned with easy access by road, rail and air:

    • Road: Close to the M4, located just off the A420 between Oxford and Swindon. Swindon is approximately 7 miles west of the campus and Oxford is around 24 miles east.
    • Rail: Swindon station (just 50 minutes from London Paddington and 25 minutes from Bristol).
    • Air: Heathrow (70 miles) or Bristol (60 miles).
