Heat Capacity: A fluid’s heat capacity indicates how much thermal energy it can transport and store, impacting the efficiency of the heat transfer process. [ 2 ] Thermal Conductivity and Thermal Diffusivity : These properties influence the rate at which heat is transferred through the fluid, affecting how quickly a system can respond to ...
In thermofluids dynamics, the bulk temperature, or the average bulk temperature in the thermal fluid, is a convenient reference point for evaluating properties related to convective heat transfer, particularly in applications related to flow in pipes and ducts.

These thermal greases have low electrical conductivity and their volume resistivities are 1.5⋅10 15, 1.8⋅10 11, and 9.9⋅10 9 Ω⋅cm for 860, 8616 and 8617 respectively. The thermal grease 860 is a silicone oil with a Zinc Oxide filler and 8616 and 8617 are synthetic oils with various fillers including Aluminum Oxide and Boron Nitride.
In thermal fluid dynamics, the Nusselt number (Nu, after Wilhelm Nusselt [1]: 336 ) is the ratio of total heat transfer to conductive heat transfer at a boundary in a fluid. Total heat transfer combines conduction and convection. Convection includes both advection (fluid motion) and diffusion (conduction). The conductive component is measured ...
Therminol is a synthetic heat transfer fluid [1] produced by Eastman Chemical Company. Therminol fluids are used in a variety of applications, including: [2] Hydrocarbon processing (oil and gas, refining, asphalt, gas-to-liquid, etc.) Alternative energy and technologies (concentrated solar power, biofuel, organic Rankine cycle, desalination, etc.)
Fluid mechanics can be divided into fluid kinematics, the study of fluid motion, and fluid kinetics, the study of the effect of forces on fluid motion. Fluid mechanics can further be divided into fluid statics, the study of fluids at rest, and fluid dynamics, the study of fluids in motion. Some of its more interesting concepts include momentum ...
where the real heat transfer rate can be determined either from the cold fluid or the hot fluid (they must provide equivalent results): ˙ = (,,) = (,,) Effectiveness is a dimensionless quantity between 0 and 1.
