Overview

What is he best known for?

The fields of study he is best known for:

  • Thermodynamics
  • Mechanical engineering
  • Organic chemistry

Shigeru Koyama spends much of his time researching Adsorption, Thermodynamics, Activated carbon, Chemical engineering and Ethanol. Shigeru Koyama has included themes like Cooling capacity, Cooling cycle, Coolant and Silica gel in his Adsorption study. His Thermodynamics research focuses on Refrigerant, Pressure drop, Chiller, Waste heat and Heat pump.

His study in Activated carbon is interdisciplinary in nature, drawing from both Highly porous, Porosity, Fiber, Sorption isotherm and Carbon. In his research on the topic of Chemical engineering, Graphite and Thermal conductivity is strongly related with Composite number. His Ethanol research is multidisciplinary, incorporating elements of Desorption, Fick's laws of diffusion, Metal-organic framework and Water cooling.

His most cited work include:

  • Waste heat driven dual-mode, multi-stage, multi-bed regenerative adsorption system (192 citations)
  • A new generation cooling device employing CaCl2-in-silica gel–water system (173 citations)
  • An experimental study on condensation of refrigerant R134a in a multi-port extruded tube (155 citations)

What are the main themes of his work throughout his whole career to date?

His primary areas of study are Thermodynamics, Adsorption, Refrigerant, Heat transfer and Mechanics. His Heat transfer coefficient, Condensation, Coefficient of performance, Heat pump and Heat flux investigations are all subjects of Thermodynamics research. His Adsorption research incorporates themes from Ethanol and Chemical engineering.

His study looks at the relationship between Refrigerant and topics such as Evaporator, which overlap with Refrigeration. His research investigates the connection with Heat transfer and areas like Pressure drop which intersect with concerns in Hydraulic diameter. His research in Activated carbon focuses on subjects like Waste heat, which are connected to Process engineering and Waste management.
