Stream water temperature is an important key factor for water quality of rivers. Different approaches for stream temperature modeling have been developed over the past few decades and can basically be grouped into heat balance and stochastic models. Energy ...
Experimental flow boiling heat transfer results are presented for horizontal 1.0 and 2.2 mm I. D. (internal diameter) stainless steel tubes for tests with R1234ze(E), a new refrigerant developed as a substitute for R134a with a much lower global warming po ...
The climate in the Sahel is marked by the spatial and temporal variability of rainfall. As the agriculture is mainly rainfed in Burkina Faso, the information about rainfall is crucial to help the farmers in their decisions. A network of wireless sensorscop ...
The diffusive regime of double-diffusive convection generates staircases consisting of thin high-gradient interfaces sandwiched between convectively mixed layers. Simultaneous microstructure measurements of both temperature and conductivity from the stairc ...
Neutron diffraction, magnetic susceptibility, specific heat, and dielectric constant measurements of single-crystal Co3TeO6 have been measured to study the interplay between the ferroelectricity and magnetic order. Long-range incommensurate magnetic order ...
Transient modeling and regulation of a two-phase on-chip liquid pump cooling cycle is studied. The purpose is to cool down multiple micro-processors in parallel and a set of memories, DC/DC converters in series. The cycle will be incorporated in a blade/dr ...
The pressure drops of external flow over enhanced tube bundles were experimentally obtained at both adiabatic and diabatic conditions using R-134a and R-236fa as test fluids. The tests were carried out at saturation temperatures of 5 and 15 degrees C, mass ...
We report a long-wavelength helimagnetic superstructure in bulk samples of the ferrimagnetic insulator Cu2OSeO3. The magnetic phase diagram associated with the helimagnetic modulation inferred from small-angle neutron scattering and magnetization measureme ...
We report the synthesis, structure, and physical properties of single crystals of CePt2In7. Single crystal x-ray diffraction analysis confirms the tetragonal I4/mmm structure of CePt2In7 with unit cell parameters a = 4.5886(6) Å, c = 21.530(6) Å and V = 45 ...
A new type of district energy network capable of providing simultaneously heating and cooling is being investigated. It is based on the use of CO2 as a heat transfer fluid by taking advantage of the latent heat of vaporization, to store and transfer heat a ...
