The phrase "a three phase model" is correct and usable in written English.
It can be used when describing a framework or system that consists of three distinct phases or stages.
Example: "The research was conducted using a three phase model to analyze the data effectively."
Alternatives: "a tri-phase model" or "a three-stage model".
These values are subject to change when a three phase model of residual oil, gas and water is considered in simulations.
Semicrystalline polymers have to be described by a three phase model consisting of a mobile amorphous (MAF), a crystalline (CF), and a rigid amorphous fraction (RAF).
Several papers [29, 30] show that the TCP goodput as well as the MAC bit rate has a specific shape, which follows a three phase model, for drive through connections.
From the analyses based on this model and one-dimensional electron density correlation function with a three phase model, the phase structure in the crystalline state of the neat LEI was concluded to be a regular lamellar structure consisting of crystalline lamella of PE block and amorphous layers of PE and PIp blocks.
Finally, a three phase model is proposed since there is evidence of a rigid amorphous phase present in PEN biaxially stretched samples which was favoured by the dependence of dielectric relaxation strengths on the degree of crystallinity for the β∗- and α-relaxation.
In contrast, T1ρ measurements indicate that oriented PGA is 50% crystalline and can be adequately described by a three phase model consisting of: rigid crystalline material with long relaxation time, semi-rigid non-crystalline material with intermediate mobility and relaxation time and highly mobile non-crystalline material with the shortest relaxation time.
Moreover, a two phase model was suggested to describe the linear viscoelasticity of such polymer nanocomposites.
Instead, a two phase model accounting for different conductive phases in the membrane is able to describe the experimental trends.
It is a two phase model where the crack initiation is treated by a local weld notch approach.
For the semi-crystalline samples used in this study, PVA obeys a two phase model in which ϕRA ∼0.
A two phase model proposed for accounting for linear viscoelasticity of polymer nanocomposite melts [14] is applied to rubbers filled with nanoclay and conventional fillers (carbon black and silica) to probe mechanisms of the fluid- and the solid-like behaviors beyond the terminal flow region.
