Thermal Engineering and Gas Dynamics Definition

Thermal engineering is concerned with heat transfer and energy conversion processes, whereas gas dynamics is concerned with the behaviour of gases in motion, particularly with regard to propulsion and fluid flow.

Contribution to Energy Conversion and Fluid Behaviour

Thermal engineering and gas dynamics are critical in designing energy conversion systems and understanding fluid behaviour in a variety of applications.

Understanding Fluid Flow and Its Impact on the Environment

Gas dynamics provides insights into fluid behaviour, assisting in the design of efficient pipelines, pumps, and turbines while taking environmental impact into account.

Renewable Energy Technology Innovations

Thermal engineering concepts are critical in the development and advancement of renewable energy technologies such as solar thermal systems and geothermal power plants.

JSME has decided that a new conference series, Pacific Rim Thermal Engineering Conference (PRTEC), will be launched collaborating with the Korean Society of Mechanical Engineers (KSME) and the American Society of Thermal and Fluids Engineers (ASTFE). The key themes of PRTEC 2016 are "Fundamental", "Interdisciplinary" and "Diversity" with a vision for the future of Thermal Engineering.

The PRTEC 2016 provides an international forum for the exchange of new ideas and direction related to the future thermal engineering and the presentation of the latest work in this field. We strongly encourage attendance and extended abstract submission not only from the Pacific-rim countries but also from all over the world.

It is known that the study of the processes of heat generation and propagation, as well as its transformation into other types of energy, led to the discovery of fundamental physical laws. We should remember, first of all, the laws of thermal radiation, the discovery of which just over a century ago radically changed physics as a science and became the basis of incredible technical advances. The revolution in theoretical physics has greatly accelerated research in heat transfer and various applications, especially in thermal engineering. Textbooks usually distinguish three ways of heat transfer: conduction, convection, and thermal radiation. However, attempts to solve real problems show that we are usually dealing with combined heat transfer, when different modes of heat transfer interact with each other.

In my opinion, thermal radiation is closer to fundamental science and appears to be a more global phenomenon than other modes of heat transfer. It is not even the fact that life on our planet exists because of thermal radiation from the Sun, and this radiation extends 150 million kilometers to reach the Earth. Contrary to popular belief, thermal radiation turns out to be important at any temperature and at any distance, and its spectrum includes the microwave range used in remote sensing of the ocean surface. This explains why we focus on radiative and combined heat transfer, and the variety of problems involved is so great.

The classical theory of radiative transfer in such media is based on the integrodifferential equation, which was independently derived early last century by Orest Khvolson and Subrahmanyan Chandrasekhar in connection with the study of radiative transfer in stellar photospheres (Chandrasekhar 1960; Rosenberg 1977). A modern systematic account of the theory of radiative heat transfer can be found in textbooks by Howell et al. (2021) and Modest and Mazumder (2021), and an engineering approach to modeling radiative and combined heat transfer in disperse systems is discussed in Dombrovsky and Baillis (2010).

The radiative transfer equation in a scattering medium does not take into account the wave nature of electromagnetic radiation, which appears most strongly when the radiation is scattered by particles whose size is of the same order of magnitude as the wavelength of the radiation. However, the wave properties of the medium are taken into account in the coefficients of the equation. In the simplest case of homogeneous spherical particles and with independent scattering (Mishchenko 2018), these properties can be calculated using the rigorous Mie theory. The general solution obtained by Gustav Mie in 1908 and useful approximate theoretical models are described in detail in a well-known monograph (Bohren and Huffman, 1998). At present, similar solutions have also been obtained for optically inhomogeneous particles of complex shape.
