Aims

Power Engineering and Engineering Thermophysics (PEET) is an international, peer-reviewed, open-access journal devoted to the study of energy conversion, thermal transport, thermofluid processes, and engineering systems governed by thermophysical mechanisms. The journal publishes research on the modelling, analysis, design, optimization, and experimental investigation of systems in which heat transfer, fluid flow, energy transformation, and related physical processes play a central role.

Engineering systems in power, energy, thermal management, process engineering, buildings, transportation, and environmental applications increasingly operate under conditions where thermal and fluid phenomena interact with material behaviour, system configuration, control strategies, and operating constraints. PEET provides a forum for research that examines these mechanisms in a rigorous and technically meaningful manner, with attention to their influence on efficiency, stability, reliability, durability, and overall system performance.

The journal is concerned with the physical interpretation and engineering consequences of thermal, fluid, and energy-related processes at both component and system levels. Emphasis is placed on clearly stated modelling assumptions, sound analytical or experimental procedures, reproducible results, and demonstrable contribution to engineering understanding. Submissions should extend beyond routine numerical implementation, limited parametric comparisons, or descriptive case reporting, and should offer substantive insight into thermophysical behaviour, energy conversion processes, modelling approaches, or system-level performance.

While particular attention is given to power engineering and engineering thermophysics, the journal also considers high-quality studies in adjacent engineering fields where thermal transport, energy use, thermofluid behaviour, or thermophysical performance is an essential part of the research question. Studies in which the energy or thermal component is only incidental are generally outside the journal’s primary scope.

Contributions may be theoretical, computational, experimental, or integrative. PEET welcomes original research articles, review articles, and well-documented studies that combine physical reasoning with appropriate analytical, numerical, or experimental support. Regardless of approach, manuscripts are expected to demonstrate technical depth, methodological transparency, and clear relevance to engineering practice or scientific understanding.

PEET is published by Acadlore. All submissions undergo structured peer review to ensure technical soundness, analytical consistency, and clarity of presentation.

Key features of PEET include:

• The journal focuses on engineering systems in which energy conversion, heat transfer, thermofluid behaviour, and thermophysical processes are central to performance.

• It addresses both component-level and system-level problems, ranging from heat exchangers, thermal storage devices, porous media, fluids, and engineered materials to power systems, renewable energy systems, buildings, vehicles, and industrial processes.

• Contributions are expected to connect physical mechanisms with appropriate modelling, simulation, experimental validation, or system analysis.

• Both fundamental studies and application-oriented investigations are considered, provided they demonstrate clear technical substance and explicit relevance to energy, thermal, or thermophysical engineering.

• Particular attention is given to reproducibility, transparent assumptions, validation where appropriate, and meaningful interpretation of results.
