Heat Transfer Coefficient for Hydrogen Flowing
On the heat transfer coefficient of hydrogen flow
The mystery of learning, in the theory of heat transfer, the heat transfer coefficient of hydrogen flow is an important study for scholars.
Hydrogen is light in weight and active, and its heat transfer in the flow is specific. To understand its heat transfer coefficient, one must first observe its flow state. If it is a laminar flow, the fluid particles go their own ways, such as silk strands, and the heat transfer is mainly conducted by molecules. Its heat transfer coefficient is related to the physical properties of the fluid, such as thermal conductivity and viscosity, and is also related to the geometry and size of the flow channel. When the path of the flow channel and the roughness of the wall change, the heat transfer coefficient also changes.
If the hydrogen flow is in a state of turbulence, the particles of the fluid are mixed with each other and turbulent. At this time, heat transfer depends not only on molecular conduction, but also on the effect of vortex diffusion. The strength of turbulence and the prosperity of vortices all increase the heat transfer coefficient sharply. The flow rate of the fluid has a huge impact on the heat transfer coefficient during turbulence. With rapid increase, the particles are mixed more fiercely, the faster the heat transfer, the larger the coefficient.
And the change of temperature also affects the heat transfer coefficient of the hydrogen flow. When the temperature rises, the viscosity or drop of the fluid, the thermal conductivity may change, and the heat transfer coefficient is different from usual. The effect of pressure cannot be ignored. When the pressure changes, the density and physical properties of the gas all change, and the heat transfer coefficient is naturally different.
To determine the heat transfer coefficient of hydrogen flow, an experimental method is indispensable. Set up an exquisite device to control the flow state, temperature degree, pressure force, measure the temperature difference between the wall and the fluid, and measure the heat transfer to calculate the heat transfer coefficient. However, in the experimental environment, it is difficult to be practical, so the theoretical deduction and numerical simulation are also helpful. According to the principle of heat transfer, build an accurate model and calculate the value of the coefficient based on the number.
In summary, the heat transfer coefficient of hydrogen flow is affected by the flow state, physical properties, temperature and pressure. Scholars should study physics intensively, combine experiments, theories, and simulations to understand the mysteries, and advance the technology of energy and heat transfer for the benefit of the world.
