Most Distinguished Achievement Award

Tim has made and continues to make an outstanding contribution to mechanical engineering at national and international levels in areas such as climate change, energy and environmental issues. His efforts have influenced policy makers at a high level and raised the profile of mechanical engineering thus capturing the attention and respect of the engineering community and wider public as a whole. 

Career including professional roles & responsibilities

• Prior to becoming a Chartered Engineer in 2001, Tim’s professional career was spent in the rapidly emerging engineering design and process simulation software sector of the 1980s/90s with a focus on developing and delivering pioneering products to a broad range of end user customers in the process industries. The latter included clients in cryogenic industrial gases, upstream and downstream oil & gas, petrochemical and chemical processing, nuclear reactor processes, pharmaceuticals, wastewater treatment and food processing. During this period, technical and managerial accomplishments were numerous and included the publication of 19 peer reviewed papers, 8 conference papers, dozens of technical reports and trade press articles, as well as senior management appointments at “Head of” and “VP” level with global responsibilities.

   

  Achievements & accomplishments

  Subsequent to the award of CEng MIMechE, accomplishments as an engineering professional have included:

• 2001 – 2007, appointments to multiple Board level roles (ie Director, Group Commercial Director and Managing Director) with global responsibilities in large organisations
• 2007 – 2014, appointed as Head of Energy and Environment at the IMechE.
• 2010 - Awarded FIMechE.
• 2015 - Established independent consultancy as an internationally recognised expert in clean energy, climate change mitigation and adaptation, sustainability and the circular economy.
• 2015 – 2018 - Chair, IMechE Food and Drink Engineering Committee.
• 2018 - Established Process Industries Division’s India Technical Centre in Mumbai, India.
• 2018 – 2021 - Chair, IMechE Process Industries Division Board.
• 2021 – 2022 - Established IMechE Climate Change Adaptation Working Group and currently leading as the initial Chair.
• Benefit to society: Extensive written and visual media work delivered for the Institution in the areas of climate change mitigation and adaptation; the sustainable use of resources, including waste management and the circular economy; pollution mitigation; and resilience. In this regard, has been the lead-author on 14 IMechE thought leadership reports, 19 policy statements, numerous government related consultation responses, opinion pieces and blogs, lead IMechE author or co-author of 5 peer reviewed papers and 2 book chapters, and given dozens of public talks, conference presentations and press, media and film documentary interviews on behalf of the Institution on these topics. 
• Delivering this contribution has depended on building consensus amongst relevant Process Industries Division Board members and members of the Board’s TACs, along with members in topic relevant Divisions and Groups across the Institution (primarily Power Division and the EESG). As well as providing thought leadership on challenging societal issues that form the context for the professional work, such as global population growth and demographic and geopolitical change. The work often involved soliciting subject matter input from experts in allied disciplines (such as physical, social, and behavioural scientists, economists, architects, etc) and resolving strong differences of opinion amongst members while maintaining technical rigour and professional integrity to present various publics with an unbiased, independent engineering-based view on complex and challenging issues. Audiences have included national government policymakers both in the UK and overseas, international bodies such as the UN and World Bank, policy influencers, commentators and opinion formers, NGOs, academia, our own and other allied professions, press and broadcast media journalists and the broader general public.
• Most notable reports and policy statements have included “Rising Seas: The Engineering Challenge” (2019); “Heat Energy: The Nation’s Forgotten Crisis” (2015); “A Tank of Gold: Cleantech Leapfrog to a More Food Secure World” (2014); “Small Modular Reactors: A UK Opportunity” (2014); “Energy Storage: The Missing Link in The UK’s Energy Commitments” (2014); “Geothermal Energy: UK Potential” (2013); “BECCS for Electricity: Land-Use Tensions” (2013); “UK Plutonium: The Way Forward” (2013); “Global Food: Waste Not, Want Not” (2013); “UK Energy: Shale Gas” (2012); “Air Capture” (2011); “Population: One Planet, Too Many People?” (2011); “CCS: Natural Gas Power Plants” (2010); “Climate Change: Adapting to the Inevitable” (2009).
• The impact of the contribution upon the profession has been to increase our profile with national and international policymakers, NGOs, allied professions and the general public, in areas that matter to society such as food, water, energy, the built environment, climate change and broader environmental risk, sustainability and community resilience, and the integration of our thinking, findings and recommendations into government policy and the work of other bodies and academia. Evidence for example numerous invitations to sit on national and international committees, requests for our input into national and international initiatives such as the UK Climate Change Risk Assessments, and the widespread use of our reports in academic teaching.

A series of innovative designs introduced by Lyndon under a title of ‘Lynflow Technology’ Including:

• Lynflow Bins - Moulded IBC bins of “Mixed Flow’ design that exploit dual plane-flow construction
• Lynflow Paddles - Paddles for continuous mixers employing tangential leading edge and ribbon trailing blade, to direct material away from the shaft and reduce the tendency to clog with sticky materials.
• Lynflow Inserts - Hopper inserts that avoids a ratholing tendency by changing the flow stress system from similarity to a thick wall cylinder subjected to internal pressure to a deep, curved beam subjected to uniform distributed load.
• Lynflow Tuned Reeds - Vibrating reeds that exploit the natural frequency of a cantilevered beam to transfer energy from the outside of a bin to the surface of a potential arch in a bulk storage bin.
• Lynflow De-aerator - Devices to accelerate de-aeration by providing shorter and easier paths for air to escape, whilst injecting air in controlled volume to avoid settlement to a cohesive condition and secure an optimum flow state.
• Lynflow Lump breaker - A machine with staggered blades that progressively crush agglomerates with a three-stage action that places fixing welds in shear, rather than tension.
