Lea CFD Associates Ltd.

Experience

Chris has a wealth of experience in CFD, in particular for health and safety applications, including many national and international contacts. His experience includes:

• Application of ANSYS CFX, CFX-5 and CFX-4 for physically complex flows - fire and smoke movement, high pressure gas leaks, thermal hydraulics - in complex geometries.
  
  
• Independent assessment of CFD in nuclear, offshore, chemical, gas-fired power plant, and tunnel fire, safety cases.
  
  
• 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
  
  
• Co-authorship of guidance on the evaluation of models for the dispersion of LNG vapour, 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 
  
  
• Invited lecturer at Nottingham University CFD Summer School
  
  
• Main author of a book published in 2007 by NAFEMS on the modelling of smoke movement in complex enclosed spaces using CFD. See http://www.nafems.org/publications/browse_buy/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
  
  
• 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.
  
  
• Active at National and European level in setting standards for CFD, leading to production of best practice guidance.
  
  
• Design of experiments, from lab-scale to field trials, to generate data for CFD model validation.
  
  
• Project management of the CFD elements of a major study on re-assessment of chlorine risks from water treatment works.
  
  
• 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. See http://eddie.mech.surrey.ac.uk/homepage.htm
  
  
• Planning and delivery of training on the basics of CFD for newcomers to the technology.
