MCHE Cylinder Flow Animation

Overview

A short 3‑D illustration of an MCHE (Mechanical Compression Heat Exchanger) cylinder showing simultaneous upward natural‑gas flow on the left side and downward mixed‑refrigerant flow on the right side. The key takeaway is the counter‑current flow pattern inside the exchanger.

Phases

#	Phase Name	Duration	Description
1	Intro	~3s	Camera pans to reveal a semi‑transparent cylinder representing the MCHE. The title label "MCHE 31‑EM‑4501" fades in above the cylinder.
2	Gas Flow	~5s	An orange arrow representing natural gas appears on the left side of the cylinder, moving from bottom to top. The label "Natural Gas" slides in from the left and stays beside the arrow.
3	MR Flow	~5s	A blue arrow representing mixed refrigerant appears on the right side, moving from top to bottom. The label "Mixed Refrigerant" slides in from the right and stays beside the arrow.
4	Outro	~2s	All elements hold for a moment, then the whole scene gently fades out.

Area Descriptions

Area	Content	Notes
Top	Title label "MCHE 31‑EM‑4501" positioned just above the cylinder	Fades in at start of Intro phase
Left	Semi‑transparent cylinder (left half) with orange upward arrow and its label	Arrow animates from bottom to top; label appears with a slight slide
Right	Same cylinder (right half) with blue downward arrow and its label	Arrow animates from top to bottom; label appears with a slight slide
Bottom	Optional caption "Counter‑current flow" (small font)	Appears with the first arrow and remains throughout

Notes

• Use a single ThreeDScene class; all objects are added to the same scene.
• Set the camera orientation to $\phi = 75^{\circ}$ and $\theta = -45^{\circ}$ for an isometric view.
• Cylinder should have fill_opacity=0.3 and a neutral gray color to keep focus on the colored flow arrows.
• Arrows should be created with Create animation; labels with Write or a brief FadeIn.
• Keep total runtime under 15 seconds to maintain brevity.
• No additional textual narration is required beyond the on‑screen labels.
