Heat & Mass Transfer

Thermal operations interact with most other physical systems, and effective design starts with a thorough comprehension of host processes and operational objectives. Heat & mass transfer mechanisms act together in direct contact systems such as gas scrubbing & quenching, evaporative cooling, product drying and psychrometric processes.

The Literature

Perry & Chilton’s Chemical Engineers’ Handbook provides a comprehensive and concise review of thermal design topics and, following a straightforward introduction of fundamental concepts, the thermal design of many types of special heat exchangers is described in accessible terms. For generations of heat transfer design engineers, other much-respected vade mecums include William H McAdams’ Heat Transmission, Donald Q Kern’s Process Heat Transfer, and Herman J Stoever’s Applied Heat Transmission – all giving a different slant on the subject from a common ground. While The Industrial Cooling Tower by K K McKelvey and Maxey Brooke has probably not been bettered, Jackson’s Cooling Towers with Special Reference to Mechanical-Draught Systems is a clear and direct primer on heat and mass transfer equipment generally. The Heat Exchanger Design Handbook edited by UK authority, Geoffrey F Hewitt FRS, has passed through many editions and is the most exhaustive reference in its field. David Butterworth FREng, has made his clear and concise Introduction to Heat Transfer openly available for download through the UK Heat Transfer Society. Various titles by Frank Incropera, David DeWitt and J P Holman make up a large body of recent literature by US authors, and are directed principally toward students entering the subject.

Art & Science

The calculation of heat exchangers characterises the iterative nature of Engineering Design very well. As remarked in the (unattributed) introduction to the topic in Perry & Chilton: “Heat exchanger design is not a highly accurate art under the best of conditions." It is a procedure in which the heuristics of the design process and the empiricism of scientific method are qualified with as much knowledge and understanding of the field as may be brought to bear. We have undertaken several expert witness and forensic investigations on those grounds.

Activities and Workscope

Dove Thermal’s expertise covers all aspects of process heat transfer design: the theoretical tools and practices by which they may be described, and the practical ability to resolve situations in which they are either not being understood or have been incorrectly applied. We research, design, investigate, model and create practical solutions to meet practical requirements, and have built many types of special heat exchangers for a wide application base. Our experience as heat transfer consultants underlies a broad range of manufacturing processes - and the means by which they may be realized. Dove Thermal Engineering has the capability to build, commission and maintain the production plant and services equipment to enable them.
