By default, your LaTeX document has a Chapter name (Chapter 1, Chapter 2, etc.) for each chapter. If you want to remove such chapter name from your document, then you can use titlesec package and define the titleformat in order to hide the chapter title.
Below are two code samples: one which shows the chapter name and the other which removes the chapter name using titlesec package.
LaTeX code showing chapter name
\documentclass{report}
\usepackage{titlesec}
\usepackage{lipsum}
\begin{document}
\chapter{Introduction}
\lipsum[2-4]
\end{document}
Output:
LaTeX code removing chapter name using titlesec package
\documentclass{report}
\usepackage{titlesec}
\titleformat{\chapter}[display]
{\normalfont\bfseries}{}{0pt}{\Huge}
\usepackage{lipsum}
\begin{document}
\chapter{Introduction}
\lipsum[2-4]
\end{document}
Output:
Hope this helps.
Thanks.
