Dr. Seamus O'Shaughnessy

Ussher Assistant Professor (Mechanical & Manuf. Eng)

I am a Mechanical Engineer with over 13 years research experience in the field of fluid mechanics and heat transfer. I graduated with first class honours from the Dept. of Mechanical & Manufacturing Engineering in Trinity College Dublin in 2006 before pursuing a PhD, during which I studied a form of natural convection termed thermocapillary or Marangoni convection. I used a combination of analytical, numerical, experimental and computational techniques to validate my research findings, which have been published in several peer-reviewed journals. In 2010 I was appointed to the role of Research Fellow in TCD, and since then I have been working on a variety of research projects, many of which involve collaborations with industry partners on interdisciplinary topics, such as an investigation of novel methods of cooling biomedical grade polymers during machining processes. Since 2011, my main research focus has been on energy and sustainable international development. My research team is involved in a project in Malawi which aims to bring off-grid electricity to those in the developing world by using the waste heat produced during cooking. Termed the muPower TEG-Stove, this research is in its 8th year and growing. In September 2016 I began my role as Ussher Assistant Professor in Energy & Sustainable International Development. I am currently working towards establishing new international development energy-related projects in countries such as Benin and Tanzania. A key focus of my research is the thermal management of the batteries used in electric vehicles, which is investigated through the use of pulsed liquid flows and two-phase mechanisms of boiling and condensation.
