Numerical investigation of bubble-induced marangoni convection
O'Shaughnessy, Seamus (2009)The liquid motion induced by surface tension variation, termed the thermocapillary or Marangoni effect, and its contribution to boiling heat transfer has long been a very controversial issue. In the past this convection ... -
Organic-based flexible thermoelectric generators: From materials to devices
Pakdel, Amir; O'Shaughnessy, Seamus (2022)There is a rapidly growing demand for self-powered technologies in wearable electronic devices that can be integrated with the human body to accomplish various functions. Flexible thermoelectric generators produce electricity ... -
Performance analysis of a prototype small scale electricity-producing biomass cooking stove
O'Shaughnessy, Seamus; Robinson, Anthony (2015)An electrical generator has been integrated with a locally produced, biomass-fed clay cooking stove in rural Malawi. The generator produces small amounts of electricity based on the thermoelectric effect. Five demonstrator ... -
Performance evaluation of thermoelectric generators under cyclic heating
O'Shaughnessy, Seamus (2021)The effect of thermal cycling on thermoelectric generator (TEG) performance is investigated for six nominally identical samples subjected to the same heating cycle profile. All TEGs experienced performance degradation, ... -
Simulation-Driven Design of a Passive Liquid Cooling System for a Thermoelectric Generator
O'Shaughnessy, Seamus; Robinson, Anthony (2017) -
Small Scale Electricity Generation from a Portable Biomass Cookstove: Prototype Design and Preliminary Results
O'Shaughnessy, Seamus; Robinson, Anthony (2013)The World Health Organisation estimates that over 20% of the global population (~1.4 billion people) lack access to electricity. Furthermore, 40% of the global population (~2.7 billion people) rely on the traditional use ... -
Thermal cycling of thermoelectric generators: The effect of heating rate
O'Shaughnessy, Seamus (2019)Thermoelectric generators, or TEGs, are solid state devices which can convert heat directly into electricity according to the Seebeck effect. When thermoelectric generators are subjected to thermal cycling they can undergo ...
