  • Why evaluate hydraulic fluid compatibility?

    When introducing a new control fluid to hydraulic systems, it is important to ensure that the new liquid or mixture is of equal or superior quality to the previous fluid. If the new mixture is incompatible, precipitate may form and result in an overall inferior fluid. This can speed up clogging or damage the system. When a manufacturer of construction machinery releases a new line of bulldozers ...

  • Time resolved liquid scintillation counting: (TR-LSC™) for environmental 3h analysis

    Environmental analysis of many naturally occurring and man-made, beta emitting radionuclides, including 3H, 14C, 90Sr/90Y, 241Pu, and 234Th is a significant analytical challenge due to the extremely low activity levels encountered. Under these circumstances, reducing instrument background is essential for improving analytical sensitivity. Time-Resolved Liquid Scintillation Counting (TR-LSC), a ...

  • Optimal finite element modelling for modal analysis of liquid storage circular tanks

    Model analysis of liquid storage vertical tanks is a complex task due to fluid–structure–soil interaction. Analysis of tanks subjected to earthquake excitations using finite element modelling (FEM) has become a preferred technique. The FEM is validated by comparing its results with experimental and theoretical results in the literature. However, most finite element studies in literature do not ...

  • Mercury Analysis

    Characteristics of Mercury What is Mercury? Mercury is a naturally occurring silver-colored metallic element noted for its occurrence as a liquid at room temperature and toxic to living organisms. This silvery, opaque liquid metal is very dense, yet has a high surface tension that causes it to form tiny perfect spheres in the pores of the rocks it is found in. It is ...

  • Second law analysis of a gravity–driven liquid film flowing along an inclined plate subjected to constant wall temperature

    The second law analysis of a gravity–driven liquid having temperature–dependent viscosity and flowing along an inclined heated plate was studied. The computational fluid dynamics (CFD) package FLUENT was used to obtain the velocity and temperature gradients, and the results were used to determine the entropy generation rate. Different cases of inclination angle and dimensionless parameters were ...
