マッハ数

When the Mach number exceeds 0.3, fluid compressibility becomes crucial. Discover the concept of "choked flow" (Mach 1), its two major engineering advantages—easy mass flow calculation and backpressure independence—and how it works in compressible flow.

By plugging parameters like pressure, velocity, viscosity, and thermal conductivity into non-dimensional numbers, you can instantly reveal the core characteristics of a flow. Discover the most frequently used non-dimensional numbers in the fluid dynamics and heat transfer fields.
