Furthermore, since the differential equation's coefficients are time dependent (periodic), parametric instability can occur depending on the system parameters such as wave height and frequency, buoyancy, and drag coefficient.
Trip time dependent on tides.
K is temperature dependent drag stress.
The physics investigated includes: particle-wall collisions, particle-particle collisions and structure dependent drag.
(a) concentration dependent (b) time dependent.
The time-dependent numerical approaches predicted the generation and evolution of vertical structures, wakes interactions, and their effects on the drag, lift, and heat transfer in the range of 20 < Re < 180.
Test results indicate that the coupled effect of changes in level of fluidity and drag force resulting from the use of different SCMs types and replacement rates affect the time-dependent stability characteristics.
By linearizing the wave drag force, the riser's lateral deflection is obtained through a partial differential equation containing a time-dependent coefficient.
time-dependent calculation.
