Full Description
I Will Simulate Solute Redistribution and Interface Stability in Your Directional Solidification Process
What you get
I will simulate solute rejection, concentration profiles, and impurity enrichment during directional solidification of your material system.
Deliverables:
- Solute concentration profile (Scheil equation + BPS effective partition coefficient)
- Enrichment ratio vs solidification rate
- Effective partition coefficient analysis (solute trapping effect)
- Boundary layer concentration profile
- 4 publication-quality figures (PNG/PDF)
- Brief interpretation report (PDF)
Example output: Al-Cu alloy
Parameters: k0 = 0.14, C0 = 4.5 wt%, D = 3e-9 m²/s
Growth rate | k_eff | Enrichment ratio
1 um/s | 0.144 | 7.42x
10 um/s | 0.185 | 7.89x
100 um/s | 0.820 | 1.88x
The low-speed enrichment of 7-8x is consistent with published Al-Cu segregation data (6-10x). At high speed, solute trapping suppresses enrichment.
What I need from you
- Material system (alloy, ceramic suspension, aqueous solution, etc.)
- Equilibrium partition coefficient k0 (or I can estimate from literature)
- Liquid diffusion coefficient D
- Boundary layer thickness delta (or typical value for your system)
- Range of growth rates to scan
Suitable for
- Alloy solidification: Al-Cu, Al-Si, Ni-based superalloys, high-entropy alloys
- Freeze casting and ice templating research
- Progressive freeze concentration (food science, pharmaceutical)
- Semiconductor crystal growth (Si, GaAs)
- Salt and mineral purification processes
- Metal additive manufacturing (melt pool solidification)
- Any material system where solute rejection or redistribution matters
Why this works
The model uses the Burton-Prim-Slichter effective partition coefficient, which captures the competition between interface kinetics (k0) and mass transport (v·delta/D). This is the same competition described in my anchoring framework: the survival factor S determines whether solute is rejected or incorporated.

If you need faster delivery, add "Express Delivery" at checkout (+$20, reduces turnaround by 2 days).
Required:
- Material system (e.g., Al-Cu alloy, NaCl-water, sea water)
- What you want to learn (e.g., "how solute enriches at different growth rates")
Optional (I will estimate from literature if not provided):
- Equilibrium partition coefficient k0
- Liquid diffusion coefficient D
- Boundary layer thickness delta
- Growth rate range (default: 1-100 μm/s for metals)
No problem. I can estimate k0 and D from literature for most common alloy systems and aqueous solutions. Just provide the composition (e.g., Al-4.5 wt% Cu) and I will handle the rest.
For uncommon systems, I may need 1-2 extra days to search the literature. No extra charge for standard estimates.
Because this is custom computational work, refunds are not available once the simulation has started.
However, I will:
- Confirm your parameters before starting
- Send you a preview of one figure before final delivery
- Offer one free revision if the output does not match your requested parameters
If you are not satisfied with the initial preview, I can cancel and refund 50%.
Yes. The figures are publication-quality (PNG + PDF, 1500×1000 minimum). You can use them in journal manuscripts, theses, or conference presentations.
The Advanced package also includes:
- Interface stability analysis (Mullins-Sekerka criterion)
- Comparison with published literature data
- Extended interpretation report
I do not write papers. I provide the modeling, figures, and interpretation you need.
