How do you reflect on a book?

how do you reflect on a book? I usually just close the book and give some thoughts to it but i feel like its not effective way to reflect by just giving thoughts. What are your suggestions? How do...

How do I get an 80 mark and above on writing a dissertation/thesis project?

I have finished my literature review and I have finished the draft of my numerical simulation(or you could say my own project). What is left is to 'beautify' my dissertation more. How do I get a...

Why are the particles concentrated in the nodal planes for only a period of time?

As you can see from the attached diagram, the particles are concentrated in the nodal planes at 0.008 s. But at 0.1s, the particles are not as concentrated in the nodal planes as at 0.008 s ( i.e....

Look into my acoustic pressure field, does it look like having an acoustic streaming?

Why is it that in the middle there are no standing wave field?How will the particles move when the standing wave field is only on the upper and lower of the cavity?

What can you deduce from my 1D plot graph of the mass fraction of suspended particles in a standing wave field?

The y-axis shows the mass fraction of the suspended particles and the x-axis shows the length of the cavity. When x = 0, that is to the left end wall of the cavity, when x = 21, that is at the...

Discrete Phase model (DPM) particle break-up has particle size limits during particle tracking?

Hello, I am currently working on simulating water droplet partciles in a closed room. When I use uniform particles, without "particle break-up", I can carry out the simulation without any problem....

Distribution of particles in metal matrix?

How would define the "good" and "poor" distribution of particles within the matrix. Is there a quantitative solution to assess the distribution of the particles, which then having denotation of...

Is there a deep reason for using the squared modulus of the wave function as the probability density of the existence of the particle?

I think we were all surprised at the first time we got to know quantum mechanics that the squared modulus of the wave function is the probability density of the existence of the particle? The role...

Zno nano particles colour changed from white to grey in process of calcination any suggestions?

In the formation of Zno nano particles process, after drying at 120 degree C, my zno nano particles are completely white but when i calcine it for 450 degree C it converts into grey colour. i...

How can I take subsamples of water from a larger sample in a way that allows me to measure the iron content of the subsample?

I learned how to take subsamples with a magnetic stir bar, but I noticed iron particles stick to the bar, and I am having trouble finding a standard method to solve that problem. How can I take a...
