About BHR Group

BHR Group Limited is an independent research and technology organisation based in Cranfield near Bedford in the UK. We specialise in the fluid dynamics and mechanics, and fluid physical and chemical behaviour of industrial processes from the nano to macro scales. At the core of our business is gaining and applying knowledge of how fluids behave and using this knowledge to design or optimise processes and products for different applications. We provide our expertise to clients world-wide through consultancy; research and testing services; physical and computational modelling; technology translation; specialist training and conferences; high-pressure contract cutting tools and product development and exploitation. Our services and products are applied to solve problems for a wide range of industrial processes and sectors including chemicals, pharmaceutical, oil & gas, renewable and conventional energy sources, water and wastewater, civil engineering, defence and aerospace. Our aim is to provide innovative or optimised designs, analytical models and operating methodologies from which cost-effective and sustainable industrial processes can be developed. To do this we work closely with our clients to understand their business needs, and develop and implement practical, technical and business solutions. With sixty years of history and a uniquely experienced workforce of professional engineers, BHR Group stands as a world centre of excellence in fluid engineering. .
