Solar Washing Machine Model Configurations

Oct 3, 2020

In this post we describe the smaug models and the set up of each of the simulations

We outlined the simulations in the project description “Solar Washing Machine”

All the simulations and models are detailed on git hub smaug_wash@github

Model Parameters

Model Dimensions and Driver Location

For example see: Model include file

Name	Value	Notes
xc1	0.5 Mm	Driver location
xc2	1.27 Mm
xc3	1.27 Mm
xmax.	12.8496 Mm	Model dimensions (maximum)
ymaz	2.56 Mm	.
zmax.	2.56 Mm	.
xmin	0.2057 Mm	Model dimensions (minimum)
ymin	0.04098 Mm	.
zmin	0.04098 Mm	.
n1,n2,n3	128,128,128	Number of mesh elements for each dimension

Driver Parameters

For example : Driver source file

Name	Value	Notes
aa	0.1 m/s	Amplitude
s_period	180 s	Driver period
tdep	1	Switches tdepenedence on/off
dx,dy,dz	0.5,0.5,0.25Mm	Gaussian width of driver

Driver amplitude

$amp=aa.\exp{(-\frac{x^2}{dx^2})}\times\exp{(-\frac{y^2}{dy^2})}\times\exp{(-\frac{z^2}{dz^2})}$

$tdepx=\sin{\frac{2\pi t}{T}}$

$tdepy=\sin{\frac{2\pi (t-0.25T)}{T}}$

Veloc

$v_x=amp \times tdepx$

$v_y=amp \times tdepy$

uni2

$aa= aa\times\exp{\frac{-(t-582)}{90}}$

uni3

$aa= aa\times\exp{\frac{-(t-120.5)}{90}}$

uni4

$tdepx=\sin{\frac{2\pi t}{T}}+\sin{\frac{2\pi t}{T_2}}+\sin{\frac{2\pi t}{T_3}}$

$tdepy=\sin{\frac{2\pi (t-0.25T)}{T}}+\sin{\frac{2\pi (t-0.25T_2)}{T_2}}+\sin{\frac{2\pi (t-0.25T_3)}{T_3}}$

$aa= aa\times\exp{\frac{-(t-120.5)}{90}}$

Rendering examples

Note use %2B to represent +

$e^{i +\pi} =x+1$

LaTeX

\(x_{1,2} = {-b\pm\sqrt{b^2 - 4ac} \over 2a}.\)

This math is inline $a^2+b^2=c^2$.

This is on a separate line

a^2+b^2=c^2
