Thermal Engineering

Heat is a form of energy potential that can be defined in terms of temperature and mass, and - like mechanical, chemical and electrical potentials - its flow described with respect to length and time. It is transmutable with other energy formats, and pervades all dynamic systems. As an engineering fundamental, it rarely stands alone: Thermal Design is just a convenient term for a very broad church, and draws on most other disciplines.


Thermal Design

Thermal Design concerns itself with the flow of heat within-and-between solids, liquids and gases, and its transmutation with other forms of energy. Thermal effects and operations may take place on minute and massive scales, and in subminiature and enormous systems. The mechanisms of conduction, convection and radiation pervade heat transmission, combustion, and thermodynamic cycles, while heat & mass transfer deals with transport mechanisms underlying multi-phase processes.

Heat & mass transfer takes place in chemical reactions and combustion processes, gas scrubbing and quenching operations, and in psychrometric systems such as evaporative cooling and product drying. Dove Thermal Engineering was established in 1998 to address all aspects of thermal process engineering, and incorporates our previous consultancy of Dove Associates. We research, design and model practical solutions in the design of custom thermal equipment, including :

Heat Exchangers for single & multiphase operations, including shell & tube, plate, and extended surface types.
Embodied applications include chemical plant and processes, HVRAC equipment, and power generation.
Gas-fired process heaters, thermal oxidizers, and most types of heating & power boilers.
Combustion processes and equipment.


The Design Process

George Polya’s heuristics (How to Solve It – A New Aspect of Mathematical Method, 1945) mapped a stepwise approach to problem-solving that corresponds with the process of questioning and discovery embedded in the Design Method. On the other hand, Scientific Method deals in facts and how to use them.

Iteration of physical data and design ideas - and a pragmatic review of its effectiveness - characterizes the Engineering Design Process, in which analogies and iterations are the lemmas and catalysts signposting design solutions. The fundamentals of thermal design are embedded with those of fluid mechanics, and raise similar issues of development and test.

The Thermal Engineering Method is a coincidence of art and science, realizing practical configurations from empirical data and theoretical concepts. Thermal Design covers an exceptionally wide field, interacting within and across most other physical systems. The effective thermal engineering design of heat transfer equipment starts with a thorough comprehension of host processes and operational objectives.
