I am completely new to CFD, and my project based on Finite volume method. I tried lot of online tutorial, notes and some books to learn FVM but couldn't find anyone much useful.

I need urgent help how to start learning FVM and code my problem. Do I have to learn FDM first to learn FVM. Please help me and guide me what is the correct procedure to proceed. Please help me as I am completely new to this field.

An easy to understand book about this i "Computational Fluid dynamics" by John Anderson. There exist scanned versions of this book, which may be downloaded. I don't know, however, whether these are legal.

The book costs only a few books at amazon if you buy a used one.

You don't meet to learn FDM to start working in FVM. However, my opinion is that FDM is easier than FVM, but FVM has important advantages, I.e it forces local conservation. Jhon Anderson textbook is very good but I used the one from Malalasekera and another one from patankar.
Happy computations!!

The basic of fluid mechanics starts from the Reynolds transport theorem. From that, we derive the integral form of the equations. Assuming strong continuity we can express the differential form of the equations.
Following this steps, you see that FVM are natural consequence of the physical balance in the integral formulation. FDM are then a step applied to the differential form.
I suggest also the book of Peric & Ferziger for the basic issue. The book of Leveque is very good for FVM applied to hyperbolic equations

Professor Denaro explanations is perfect. Leveque's book is quite difficult to find in amazon but that books is among the best I have read. I strongly recommend that book too.

Suffices with writing in google MALALASEKERA CFD TEXTBOOK and you will read a lot of information about his books.

I think he refereed to https://books.google.com/books/about...page&q&f=false

I already purchased the one I pasted. The other one your refereed to is for hypersonic flows which is a subdivision of flows type; compressible flows with Mach number greater than 5.

I may be wrong about the book that Professor Denaro suggested; but the one I suggest is very good for FDM.

Thanks, but my work is completely focussed on FVM as my prof suggested, u working on FDM or FVM?

Thank you proff. for the information, Can you also help me with this?

As I am new to CFD, I would like to know, what is flow solver?

What are different parts of flow solver, Please explain in brief and suggest some study material.

What is your goal? If you want to be just a CFD code user, I suggest to read the Fluent tutorial and user guide. Alternatively, OpenFOAM can be read

This is a quite challenging task to be explained in this forum. My recommendation is to use Andersons Textbook, Computational Fluid Dynamics The Basics With Applications. He does not use FV, but still will be very helpful, since the book has a lot of subroutines.
