👉 The default fluid, often referred to as the base fluid or carrier fluid, is the primary substance in which other fluids or additives are dissolved and suspended to form a stable mixture. This fluid provides the essential properties such as viscosity, density, and thermal conductivity necessary for the operation of various systems like hydraulic systems, lubricants, and cooling fluids. Common examples include mineral oil, synthetic oils, and water, each chosen based on specific requirements for performance, temperature stability, and compatibility with system components.
