TīmeklisOnce the yield stress is exceeded and flow initiated, Bingham plastics behave like Newtonian fluids; as indicated in Figure 7.8, the rheogram is a straight line for τ>τ 0 and a constant ratio K p exists between change in shear stress and change in shear rate. Tīmeklis2003. gada 4. apr. · Of the averaged rheogram the frequency spectrum was calculated by means of a FFT algorithm. The power of the Fourier amplitude for each harmonic was displayed on the computer screen and stored on hard disk. The main signal energy of the impedance pulse waveform is comprised in the first ten harmonics (Filho et al. …

Tīmekliswhere τ is the shear stress, K is the consistency index, γ ˙ is the shear rate, and n is the flow behaviour index.The parameters K and n characterise the rheology of power-law fluids. The flow behaviour index n is dimensionless; the dimensions of K, L −1 MT n−2, depend on n.As indicated in Figure 7.8, for pseudoplastic fluids n<1. When n>1, … Tīmeklis2024. gada 19. dec. · Instrumentation “One point" instruments • provide a single point on the rheogram. • Extrapolation of a line through this point to the origin will result in the complete rheogram. • Used for Newtonian fluids. • Since the rate of shear is directly proportional to the shearing stress. • The capillary and falling sphere are for use only ...
