Previous mathematical models of quasi-steady turbulent plumes and fountains have
described the flow that results from a prescribed input of buoyancy. We offer a new …

The influence of ambient fluid stratification on buoyant miscible jets and plumes is studied
theoretically and experimentally. Given a fixed set of jet/plume parameters, and an ambient …

We review techniques for measuring fluid flow and advective heat output from seafloor
hydrothermal systems and describe new anemometer and turbine flowmeter devices we …

An entrainment model for lazy turbulent plumes is proposed, the resulting solutions of the
plume conservation equations are developed and the implications for plume behaviour are …

The paper deals with steady-state turbulent fountains in a homogeneous surrounding. A set
of mono-dimensional conservation equations is first derived from the Navier–Stokes …

In this paper the dynamics of the simultaneously filling and emptying of a box is studied
theoretically and experimentally. Both situations, consisting of negatively buoyant (fountains) …

The paper examines experimentally and theoretically the virtual origin position of a fire
plume in the so-called simultaneous filling and emptying box problem. Small-scale …

The emptying–filling box problem is examined theoretically in a general non-Boussinesq
case. The steady solutions are first reviewed and expressed both as a function of a pure …

The natural ventilation flow driven by an internal buoyant plume in a box involving an upper
opening (vent) located at the ceiling (for the outflow) and a large lower opening at the floor …

A new draft equation involving swirling motions for natural draft dry cooling towers
(NDDCTs) is derived and solved analytically. A 2-D axisymmetric model for a short NDDCT …
