The key intention of 1732nd International Conference on Heat Transfer and Fluid Flow ( ICHTFF-2024 ) organized by Iser. The key intention of ICHTFF is to provide opportunity for the global participants to share their ideas and experience in person with their peers expected to join from different parts on the world. In addition this gathering will help the delegates to establish research or business relations as well as to find international linkage for future collaborations in their career path. We hope that ICHTFF outcome will lead to significant contributions to the knowledge base in these up-to-date scientific fields in scope.
