## What is semi infinite medium?

Semi-infinite solid: An idealized body that has a single plane surface and extends to infinity in all directions. The earth can be considered to be a semi-infinite medium in determining the variation of temperature near its surface.

**What is pseudo steady state diffusion?**

Pseudo-steady state (or pseudo steady-state), is also referred to as “stabilized,” or as “steady state in a bounded drainage area.” This type of reservoir flow occurs much more frequently than steady-state flow or unsteady-state flow with an expanding drainage radius.

**What is the equation of semi-infinite solid?**

In this section, a formula will be derived for temperature distribution in a semi-infinite body with a convective boundary condition (Fig. 2). where u=T-{T_i} .

### What is semi-infinite plate?

In mathematics, semi-infinite objects are objects which are infinite or unbounded in some but not all possible ways.

**What is steady and unsteady state?**

Steady-state and unsteady-state processes describe the time interval that a process occurs over. Steady-state refers to the time where the variable of interest doesn’t change. Unsteady-state is when the variable of interest changes over time.

**What is steady and unsteady state flow?**

The flow parameters such as velocity, pressure, and density of a flow for each point are independent of time in a steady flow whereas they depend on time in unsteady flow.

#### What is semi steady state?

The semi-steady state flow period can be determined by observing linearly decreasing pressure everywhere. It is observed that the flow is stabilized after approximately three hours, which means the flow after that is semi-steady state.

**What is Arnold diffusion cell?**

Arnold diffusion describes the diffusion of trajectories due to the ergodic theorem in a portion of phase space unbound by any constraints (i.e. unbounded by Lagrangian tori arising from constants of motion) in Hamiltonian systems.
