Biography
Dr. Anutosh Chakraborty is an Associate Professor at the School of Mechanical & Aerospace Engineering since January 2010. He obtained his BSc (Mechanical Engineering) from Bangladesh University of Engineering & Technology (BUET) in 1997. He then obtained his MEng and PhD degrees from the department of Mechanical Engineering, National University of Singapore (NUS), in 2001 and 2005 respectively. Later he worked at the Institute for Materials, Chemistry and Engineering, Kyushu University, Japan as a lecturer for one year. He was awarded the Japan Society for the Promotion of Science (JSPS) postdoctoral fellowship in 2007. He is the PI and Co-PI of several projects funded by A*STAR MND, MCERP, MOE, NTU internal and NRF Competitive Research Program.

Research
  • Interest:
    Adsorption Thermodynamics, Adsorption/Absorption cooling, Adsorption Gas Storage and Metal Organic Frameworks, Thermoelectric cooling and power generation, Sorption Desalination
  • Projects:
    A High Efficient Waste Heat Driven Quad-generation Plant
    The quad generation plant uses saline water as refrigerant and produces chilled water (7 to 12 °C) and cooling water for process cooling and air conditioning purposes. The fresh water is collected at the condenser. The plant is environmentally benign.
    [Energy Systems Laboratory, Thermo-Fluid & Energy]
    Gas storage employing Metal organic Frameworks (MOFs)
    We have performed an extensive study on synthesis, characterization and property evaluation of MIL-101(Cr, Fe) metal-organic framework (MOF) for CH4 adsorption under LNG-ANG coupling conditions. MIL-101(Cr) exhibits high CH4 delivery capacity at 298 K.
    [Energy Systems Laboratory, Thermo-Fluid & Energy]
    Renewable Energy Based Cooling Systems
    We have demonstrated that the low grade heat source can be used to generate cooling either by chemical (sorption) or physical (ejector) methods. In these systems, the driving heat source could be provided by either a solar collector array or low temperature waste heat source.
    [Energy Systems Laboratory, Thermo-Fluid & Energy]
    Membrane-based Absorption Air-conditioning and Dehumidification System Using Renewable Energy or Waste Heat
    We have developed a LDAC and dehumidification to improve the efficiency of air-conditioning system employing membrane technology. The membrane based sorption reactor maximizes the area for water vapour transfer and minimizes conductive heat transfer.
