Food Rheology and Texture

Subtopic: Herschel-Bulkley Model

Question Statement:

The Herschel-Bulkley rheological model is expressed as:

Options:

  • (A) \tau = \tau_0 + K \dot{\gamma}^n
  • (B) \tau = K \dot{\gamma}^n
  • (C) \tau = \mu \dot{\gamma}
  • (D) \tau = \tau_0 + \eta_p \dot{\gamma}

Answer Key:

A

Step-by-Step Solution & Explanation

The Herschel-Bulkley equation $\tau = \tau_0 + K \dot{\gamma}^n$ generalizes both power law and Bingham plastic behaviors by incorporating both a yield stress $\tau_0$ and non-linear power-law flow behavior ($n \ne 1$).
