About

About OJ

Professor Ole Jørgen Nydal has a background in physics from Norwegian University of Science and Technology, (NTNU, then NTH) and fluid mechanics (Dr.Scient) from University of Oslo. His research area has been multiphase flows in pipes, first at Institute for Energy Technology and later at NTNU, where he established a multiphase flow laboratory with associated experimental and numerical research activities. He has shown a growing interest in small scale renewable energy technology the last 15 years, and has collaborated with a group of African universities in a series of Norad programs. The projects have included development of educational programs (master and PhD) and a combination of experimental and computational work on solar heat storage systems. Heat storage for cooking is a particular important application area.
