The end application of the research is the development of solar thermal desalination systems and visualization of flow mixing and gas-liquid flows in several industrial applications.
The research was partially funded by the Ministry of Defense as a techno-commercial project and Thermex SPX Energy Technologies Ltd.
Indian Institute Researcher technology Jodhpur invented a technique to measure boiling point and condensation heat transfer using infra-red thermal imaging technology. The main objective of the research was to visualize the fluid flow and temperature distribution in multiphase flow. Its purpose was also to measure the heat transfer rate and its coefficients during boiling and condensation. Researchers at IIT Jodhpur have developed An in-house multi-electrode sensor system for tomography of liquid-gas flow and efficient desalination process using vacuum evaporation process and boiling system.
Dr. Hardik Kothadia and Dr. Arun Kumar R from the Department of Mechanical Engineering, IIT Jodhpur along with their students Mr. Sarvjit Singh, Mr. Arvind Kumar, Mr. Bikash Patnaik, Mr. Anoop SL, Ms. Aastha Gautam and other faculty members Dr. Pradyut Ranjan Chakraborty, Dr. Sakshi Dhanekar and Dr. Kamaljit Rangra.
The work was later published in the International Journal of Thermal Sciences. The research was partially funded by the Ministry of Defense as a techno-commercial project and Thermax SPX Energy Technologies Limited. An experimental study was conducted to investigate the effect of coil orientation on the local heat transfer distribution, pressure drop, and critical heat flux during flow. boil.
The study used SS-304 tubes of different diameters with horizontal and vertical orientation. The results showed that the orientation of the coils did not significantly affect the two-stage pressure drop, but did affect the wall temperature, the heat transfer distribution, and the critical heat flux. The study found that the local and average heat transfer coefficients were higher in vertical-oriented than horizontal ones.
Talking about the significance of the research, Dr. Hardik Kothadia, Assistant Professor, Department of Mechanical Engineering, IIT Jodhpur, said, “Infrared thermal imaging and multi-electrode sensor systems are unique techniques for visualization of temperature distribution and multiphase flow.”
Dr. Arun Kumar R, Assistant Professor, Department of Mechanical Engineering, IIT Jodhpur, further adds, “Multi-electrode sensor systems have many industrial applications for analyzing liquid flows and flow mixtures.”
The ultimate application of the research is the development of solar thermal desalination systems and the visualization of flow mixing and gas-liquid flows in many industrial applications. As a part of the future scope, the researchers are hoping to develop efficient and robust multi-electrode sensor systems and multi-effect desalination systems.
