Numerical Evaluation of the Efficiency of an Indoor Air Cleaner under Different Heating Conditions

open access: yesAtmosphere, 2023
For an efficient indoor air purification, it is important to know the detailed airflow distribution in the room. A series of numerical simulations are carried out for five heating regimes using an air–air heat pump, capillary mat on the ceiling ...

Modeling Transit Flow Through Port Gates and Connecting Channel in Baltic Sea—Liepaja Port—Liepaja Lake System

open access: yesFrontiers in Marine Science, 2021
This study investigates a water transport features by extending Copernicus Marine Environment Service (CMEMS) to the Liepaja coast-port-channel-lake system with a two-way nested model. The Liepaja lake and Liepaja port are connected by Trade channel. The

Thermal Comfort in Indoor Spaces with Radiant Capillary Heaters

open access: yesEnvironmental and Climate Technologies, 2022
Capillary heat exchangers are a great alternative to conventional radiators or electric heaters when used with heat pumps due to larger area and therefore a lower working temperature. In this work, we study thermal conditions in a model room using either

Influence of Salinity and Temperature Gradients on the Variability of the North Brazil Undercurrent

open access: yesFrontiers in Marine Science, 2021
The North Brazil Undercurrent (NBUC) is a narrow (<1°) northward western boundary current in the tropical South Atlantic Ocean. It carries a large volume of water (>16 Sv) and plays an important role in the Atlantic Meridional Overturning ...

An Improved Approach to Wave Energy Resource Characterization for Sea States with Multiple Wave Systems

open access: yesJournal of Marine Science and Engineering, 2022
Generally, wave energy resource assessment and characterization are performed based on an entire wave spectrum, ignoring the detailed energy features that belong to wave systems, i.e., wind waves and swells. In reality, the energy is separately possessed

Impacts of the Surface Potential Vorticity Circulation over the Tibetan Plateau on the East Asian Monsoon in July

open access: yesAtmosphere, 2023
Based on the definition of potential vorticity substance (W) and its equation, an index “iPV” representing the leading mode of the surface potential vorticity circulation (PVC) over the Tibetan Plateau is defined to characterize the orographic potential ...
