Plate heat exchangers are widely used in compact thermal systems, where heat-transfer enhancement must be balanced against hydraulic losses. This study develops a computational fluid dynamics (CFD) and regression-based surrogate framework for a novel plate heat exchanger (NPHE) under two working-fluid regimes. Three-di...
This study presents a steady-state modeling framework to analyze the axial temperature and pressure gradients, as well as the flow behavior, of cryogenic liquid CO2 transported through pipelines linking carbon capture facilities to utilization or storage sites such as enhanced oil recovery operations. A discretized o...
This study presents a thermal-hydraulic assessment of an indirect solar water heating system employing carbon dioxide (CO2) as the heat-transfer fluid in a flat-plate collector. The work compares superheated and supercritical operating regimes under identical geometric, flow, and standardized outdoor conditions. A dist...
Waste heat recovery from internal combustion engines (ICEs) is one potential option to improve overall vehicle efficiency. Rankine cycles based on engine coolant and exhaust heat sources have demonstrated their effectiveness in enhancing brake thermal efficiency. Critical to their success is the design of the heat e...
The global shift toward cleaner energy has positioned hydrogen-enriched methane (CH4/H2) as a practical bridge fuel. While it burns more efficiently and produces fewer carbon emissions than traditional hydrocarbons, it introduces operational and safety challenges. Hydrogen’s high reactivity and rapid burning velocity i...
A mathematical model was developed and experimentally validated to predict the thermal performance and drying behavior of an indirect active solar dryer (IAHSD) for mint leaves. The distinctive contribution of the proposed approach is its integration of solar-energy input, auxiliary gas heating, controlled fresh–reci...
