Colossal Barocaloric Effects at Triple‐Phase Points

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Colossal barocaloric effects were achieved in odd‐numbered normal alkane systems, such as C17H36, C19H40 and C21H44 approaching triple‐phase point by overlapping two separated phase transitions of ordered‐disordered solid phase transition and solid–liquid phase transition under a relative low pressure.

Evaluating the sensitivity of surrogate optimization target properties characterizing droplet formation, evaporation, and chemical reactions to biodiesel composition reduction

Environmental Progress &Sustainable Energy, EarlyView.
Abstract Liquid fuels contain a large number of components. However, it is not computationally feasible to implement the detailed composition into numerical solvers in combustion chamber design. Surrogate mixtures are used to facilitate calculations, which can reproduce the fuel characteristics with fewer components providing reasonable accuracy ...

A Comparative Life Cycle Assessment of Residential Heating Systems in Tehran, Iran

Energy Science &Engineering, EarlyView.
ABSTRACT Environmental pollution from different gas heating systems in residential buildings has significant impacts, especially in urban areas due to their high density. This study conducts a comparative life cycle assessment of two commonly used residential heating systems in Tehran: the Central Boiler Room (CBR) and the wall‐hung boiler (WHB). Using
