Professor Langrish is a world leader in drying technology, particularly spray drying and the drying of timber. His work, with Professor Fletcher, on transient flows in spray dryers, has uncovered new types of flow instabilities that are fundamental to improving practical outcomes in reducing the deposition of particles on spray dryer walls. This achievement is scientifically significant because it applies advanced computational modelling and physical understanding to the solution of important and common industrial process engineering problems.

His recent work to develop crystallization in drying has the potential to improve the use of resources by combining crystallization and drying, which traditionally are done separately, into one operation. The industrial significance and application of this work can be judged from the improvements in productivity and quality that have been achieved for local dairy and timber industries.

Professor Langrish served as Head of School from 2008 until 2015.
