Modeling a buoyancy-driven, air-to-air heat exchanger

Speaker: Sylvie Bronsard, NYU

Location: Warren Weaver Hall 517

Date: Thursday, April 23, 2026, 12:30 p.m.

Synopsis:

I will give an informal, practice defense talk, during which I will introduce a model for a buoyancy-driven, air-to-air heat exchanger. This model, derived from first principles, features a conservative boundary condition at inflow based on the compressible Bernoulli equation, and a dissipative boundary condition at outflow based on pressure continuity. We solve for the steady-state behavior numerically and asymptotically, with excellent agreement between the two, and we study the tradeoff between the efficiency and air flow predicted by the model.
