Lea CFD Associates Ltd.  


Chris has a wealth of experience in fluid flow modelling, in particular for major hazards and industrial safety applications, including many national and international contacts. His experience includes:

  • Engineered composite repairs: State of the art reviews for the Health and Safety Executive addressing non-destructive testing, the criticality of defects, and long-term integrity.
  • Review of dispersion, fire and explosion models for offshore hazards, for the Health and Safety Laboratory.
  • Expert witness reports for Sedgwick Detert Moran & Arnold in the successful defence of a case which turned on the modelling and analysis of fire spread.
  • Expert input on the CFD modelling of hydrogen deflagrations for the EC-funded SUSANA project, https://www.h2fc-net.eu/other-projects/susana-database/ , via the Health and Safety Laboratory.
  • Expert input on fire modelling for the OECD/NEA PRISME-2 project, https://www.oecd-nea.org/jointproj/prisme-2.html , via the Health and Safety Laboratory.
  • Application of boundary layer models in the analysis of a flow calibration device, for a UK SME.
  • Independent assessment of CFD modelling for marine current turbines, for GL Garrad Hassan
  • Analysis and reporting of Large Eddy Simulation (LES) and Unsteady Reynolds-Averaged Navier-Stokes (URANS) CFD modelling for a nuclear energy company.
  • Expert witness reports for CMS Cameron McKenna LLP on the issue of the modelling of fire spread in an aircraft hangar. https://cms.law/en/GBR/Office/London
  • Expert witness reports for Housemans Solicitors, as instructed by partner Michael Appleby - leading lawyer in health and safety law, in the case of a successful defence of a Company acquitted of charges of a breach of the Health & Safety at Work Act 1974 concerning the death of an employee. http://www.fisherscogginswaters.co.uk/about-the-team/michael-appleby/  
  • Independent assessment of CFD and other fluid flow modelling in nuclear, offshore, chemical, LNG terminals, gas-fired power plant, and tunnel fire, safety cases.
  • Application of ANSYS CFX for complex flows - fire and smoke movement, high pressure gas leaks, thermal hydraulics - in complex geometries
  • Application of jet, forced plume and buoyant plume correlations for accidental releases of flammable gas in industrial settings
  • Author of a book published in 2010 by NAFEMS https://www.nafems.org/publications/browse_buy/browse_by_topic/cfd/ht32/ providing guidance to ensure that CFD for industrial applications is fit for purpose.
  • Co-authorship of a Model Evaluation Protocol and Validation Database for LNG vapour dispersion models, with the Health and Safety Laboratory, on behalf of the US-based Fire Protection Research Foundation and in support of the NFPA 59A international standard. Reports available from the National Fire Protection Association at http://www.nfpa.org/foundation
  • Chair of Industrial Programme Committee of ERCOFTAC, http://www.ercoftac.org , 2008 to 2010, and webmaster for the ERCOFTAC website, 2009 to 2012.
  • Initiation and management of a multi-national project for the gas turbine industry, leading to co-authorship of CFD best practice guidance. See report CM/03/12, at http://www.hse.gov.uk/research/hsl/fire.htm, and CM/04/09
  • CFD modelling of high pressure gas releases on offshore platforms, using ANSYS CFX, to aid in the assessment of gas detection strategies for HVAC ducts. See HSE report RR602 at http://www.hse.gov.uk/research/rrhtm/rr602.htm
  • Assessment of CFD models for prediction of the probability of ignition of flammable gas releases
  • Evaluation of a workbook approach to modelling gas accumulation in confined and congested areas offshore. See HSL/2006/45 at http://www.hse.gov.uk/research/hsl/fire.htm
  • Project management of the CFD elements of a major study on re-assessment of chlorine risks from water treatment works
  • Active at National and European level in setting standards for CFD, leading to production of best practice guidance
  • Thematic area coordinator in EU Fifth Framework project: QNET-CFD. The objective of QNET-CFD was to develop a knowledge base of CFD solutions, data, and best practice guidance. Chris coordinated activities for the Chemical, Process, Nuclear Safety & Thermal Hydraulics sector. The database is now hosted and maintained by ERCOFTAC www.ercoftac.org  See http://qnet-ercoftac.cfms.org.uk/w/index.php/Main_Page
  • External examiner of PhD theses submitted to University of Manchester and University of Nottingham. Invited lecturer at Nottingham University CFD Summer Schools
  • Main author of a book published in 2007 by NAFEMS on the modelling of smoke movement in complex enclosed spaces using CFD.
    See https://www.nafems.org/publications/browse_buy/browse_by_topic/cfd/ht35/
  • Co-author of independent guidance on the assessment of CFD simulations of fire and smoke movement, for HSE. See HSL/2002/29 at http://www.hse.gov.uk/research/hsl/fire.htm
  • Design of experiments, from lab-scale to field trials, to generate data for CFD model validation
  • Planning and delivery of training on the basics of CFD for newcomers to the technology
