In this manuscript, a solar cavity packed with thermoelectric generator modules is investigated numerically. The hot plate of TEG modules make the inner surface of the cube, and the cold plate is outside of the cavity, under natural convection. The TEG modules are electrically in series. The solution algorithm using the equations of heat transfer and generated power of TEG modules is d...

2014 A cooled cubic cavity receiving a non uniform concentrated solar radiation is modelized, using the diffuse and semi-gray surface hypothesis and the net radiation method equations. Two more equations corresponding to the heat transfer to a cooling fluid permit to define a heat balance. Thus at thermal equilibrium, net fluxes and temperatures inside the cavity are calculated. An air-cooled s...

We show a theoretically electromagnetic induction method to detect the changes of fluid volume into an organic tissue. This method is technique to detect a phase shift through measurements of induced electrical currents due a RF signal. This method was designed for volumetric brain edema monitoring. Circular and planar magnetron coils were evaluated and compared for their ability to detect edem...

This paper presents current research on Direct Steam Generation (DSG) by the Solar Thermal Group at ANU. It includes ongoing work on a transient model for a dish steam cavity receiver that is suitable for model-based control of DSG as well as reporting on the experimental set-up on a new 500m paraboloidal dish solar concentrator. A comparison of two transient models of a dish steam cavity recei...

A model has been developed to simulate the performance of a prototype solid particle receiver that was recently tested at Sandia National Laboratories. The model includes irradiation from the concentrated solar flux, two-band re-radiation and emission with the cavity, discrete-phase particle transport and heat transfer, gas-phase convection, wall conduction, and radiative and convective heat lo...

The temperature control of direct steam generation depends on information about the dynamic heat transfer behaviour of the receiver during operation. This information may come from sensors or dynamic mathematical models of the heat transfer process taking place at the receiver. In practice, sensors are susceptible to noise and calibration errors and models suffer from uncertainty due to inexact...

The Axion Dark Matter eXperiment (ADMX) was designed to detect ultra-weakly interacting relic axion particles by searching for their conversion to microwave photons in a resonant cavity positioned in a strong magnetic field. Given the extremely low expected axion–photon conversion power we have designed, built and operated a microwave receiver based on a Superconducting QUantum Interference Dev...
