Numerical Simulation in Gas Hydrate Formation

/in /by

The formation of gas hydrates is an undesirable process in the natural gas transportation industry, ensuring the blockage of pipelines and especially the reduction of transport flows and the increase of working pressure. That is why it is necessary to simulate the water adsorption processes using chemicals as well as the mathematical simulation of the processes. The article presents data on the simulation stages and especially the behavior of natural gas with water content in main pipelines.

Comparing Solar Heater Designs: Evacuated Tube Vs. Flat-Plate Collectors

/in /by

In terms of solar heater designs, this study compares the characteristics of collectors made from evacuated tubes (ETCs) as well as collectors with flat plates (FPCs). Due to their reduced heat loss, ETCs—which have individual tubes made of glass with a sealed under-vacuum double-wall design—perform exceptionally well in colder climates. FPCs, in comparison, are more affordable but less effective since they include a simpler absorbent plate that fits inside of a flat panel. These designs can be implemented using the SolidWorks software, which permits precise 3D modeling as well as simulations. According to research, ETCs are appropriate for colder locations since their vacuum insulation reduces heat loss along maintains greater temperatures. Even while radiation losses make FPCs less efficient, they are still excellent at collecting daylight energy, specifically in warmer climates. Decision-makers looking for sustainable cooling solutions might benefit from analysis that takes into account technical characteristics, financial viability, and geographical compatibility.
