**About the Editors**

#### **Jaroslaw Krzywanski**

Jaroslaw Krzywanski (1967) is a Professor at the Faculty of Science and Technology, Jan Dlugosz University in Czestochowa, Poland. He graduated from the Czestochowa University of Technology, Department of Mechanical Engineering, Institute of Thermal Machinery, Poland, and then earned his PhD. and D.Sc. Degrees (Doctor Habilitatus) from the Silesian University of Technology, Faculty of Energy and Environmental Engineering, Poland.

He has published more than 150 refereed works, including papers, two monographs, and conference proceedings, and serves as an editorial board member of several international journals.

His research interests are modelling energy processes and devices, including adsorption cooling and desalination systems, fluidization and circulating fluidized bed technology, chemical looping and calcium looping combustion, and gas emissions, using programmed and artificial intelligence methods.

#### **Norbert Skoczylas**

Assoc. Prof. Norbert Skoczylas (1979) is a graduate of the Faculty of Electrical and Computer Engineering, Cracow University of Technology, Poland. He wrote his doctoral thesis on the use of fuzzy logic for the assessment of methane and rock outburst risk. His habilitation was based on studies of the rock-gas system using original measurement methods. In his scientific work, he studies sorption and gas transport in porous media.

#### **Marcin Sosnowski**

Assoc. Prof. Marcin Sosnowski (1979), after graduating from the Faculty of Electrical Engineering at the Czestochowa University of Technology, Poland, in 2001, started working as an assistant at the Institute of Piston Engines and Control Techniques at the Faculty of Mechanical Engineering and Information Technology at the Czestochowa University of Technology. At that time, his main scientific interests were focused on the numerical modelling and simulation of flow processes with combustion. He analysed various techniques, prepared customized procedures, and implemented them into open-source codes. He also gained practical skills and engineering know-how by supervising and operating a combined heat and power generating unit at the WARTA S.A. Central Wastewater Treatment Plant in Czestochowa. After obtaining a Ph.D. degree in Mechanical Engineering, he started working in the position of analysis engineer at the Engineering Design Center, which is the R&D centre of General Electric, where he was responsible for the development and implementation of an innovative IT tool designed for the automatic discretization of computational domains describing combustion chambers of aircraft turbine engines and gas turbines. This allowed him to optimize the implementation process of the new product, for which he obtained the Green Belt in Six Sigma process quality management certificate. He conducted numerical analyses of the flow processes with combustion. He cooperated with engineers from the United States and India on projects directly related to numerical modelling. In 2009, he started working at the Faculty of Sciences and Technology of Jan Dlugosz University in Czestochowa, where he was a post-graduate studies manager, the deputy director and director of the Institute, vice dean for student and didactic affairs, and the dean of the Faculty of Science and Technology. He participated in several projects financed from external funds as a manager or coordinator. He has published approx. 100 scientific papers as an author or co-author, and he has reviewed 100+ scientific papers for journals with assigned Impact Factors. He was the member of scientific committee or organizing committee of 30+ conferences and served as topic editor, guest editor, or member of the editorial office of approx. 20 journals. He was the manager of a scientific project entitled "Modelling of thermal contact resistance in granular materials using computational fluid dynamics" financed by the Polish National Science Centre. He participated as a research worker/contractor in projects financed by the Polish National Centre for Research and Development and the Polish National Science Centre. His scientific activity was carried out in several scientific institutions, including international scientific internships and other forms of personal exchange. A measurable effect of his international cooperation are publications co-authored by representatives of recognized scientific centres from Japan, Saudi Arabia, China, Pakistan, Ukraine, and the Czech Republic.
