A new virtual experiment environment enhances bioprocess engineering education by allowing students to design and conduct numerous simulated experiments, improving understanding of cell growth kinetics and reactor concepts.

Area of Science:

  • Bioprocess Engineering
  • Chemical Engineering Education
  • Virtual Experimentation

Background:

  • Traditional bioprocess engineering education relies on lectures and physical labs.
  • Information and Communication Technology (ICT) presents opportunities to enhance learning.
  • Understanding cell growth kinetics and reactor concepts is crucial for students.

Purpose of the Study:

  • To develop and evaluate a virtual-experiment environment for bioprocess engineering students.
  • To support both model-related and experiment-related learning objectives.
  • To provide a platform for iterative experimental design and learning.

Main Methods:

  • Development of a virtual-experiment environment simulating biological reactors.
  • Students designed experiments, setting initial conditions and measuring outputs.
