Performance evaluation and optimization guidance for steam generating heat pumps with significant temperature lift

Case Studies in Thermal Engineering
Steam generating heat pumps (SGHPs) offer a promising alternative to coal-fired boilers. To address the lack of general optimization strategy of autocascade SGHP (ASGHP) for variable operating conditions and variable cycle configurations, this paper ...

The Effects of CO₂ Additional on Flame Characteristics in the CH₄/N₂/O₂ Counterflow Diffusion Flame

Molecules, 2021
The effects (chemical, thermal, transport, and radiative) of CO2 added to the fuel side and oxidizer side on the flame temperature and the position of the flame front in a one-dimensional laminar counterflow diffusion flame of methane/N2/O2 were studied.
