Seminar «Application of enhanced boiling surfaces: From Fundamental Phenomena to Widespread Use»

Dr. Alexander Ustinov
November 25, 2013. Time slot: 13.00 – 14.30
Skolkovo School of Management – Beijing – 1 Auditorium

SEMINAR ABSTRACT:

Boiling and condensation are two core processes in power generation and to enhance them numerous surfaces had been developed and extensively investigated over the last few decades. Application of surfaces with micropins, plasma-sputtered particles or ultra-thin coatings, developed by the author, can affect industries like power generation, cooling of electronics, refrigeration, heating and air-conditioning dramatically: their heat transfer rates were measured to be up to 18 times higher than for conventional surfaces.
Physics of boiling and condensation from novel surfaces reveals unexplored fundamental phenomena, like nucleation in a form of bubble chains, see Figure 1. This phenomenon along with interface oscillations of vapor bubbles and sono-luminescence will be discussed in presentation together with an innovative experimental method of simultaneous laser and acoustic diagnostics for multiphase systems complemented by theoretical analysis using the theory of chaos.

To increase efficiency of an energy system even more, one needs to utilize low potential heat sources. A combination of a heat storage and heat recovery system (like Organic Rankine Cycle installations) will be the next topic of the presentation. Several numerical (CFD) simulations and experimental investigations, performed by the author for European companies, will be demonstrated in presentation for processes in real-life industrial devices like wet scrubbers, catalysts, exhaust-gas-recirculation (EGR) coolers, thermal-electrical generators and heat accumulators. These technologies allow creation of a virtually fully autonomous energy system for a clean and efficient energy for tomorrow.
